#solar flare homicide

[anchor-dreamss]

[madcatdaderpydrawer-blog]

Wait a fucking minute! Eclipse didn’t enter Solar Flare’s body until after Sun ran off on his homicidal rampage.

I only just realized that when someone else pointed it out

[teecupangel]

There's this manga called Brutal: Confession of a homicide investigator and when I finished it all I thought was, "Desmond in MC's place would be pretty funny especially with his bleeds lol" because with the crap Desmond went through, I feel like he should de-stress some of it in.... different ways

The manga is really brutal with some triggering stuff so it's ok if you don't do this

Nonnnnyy, I’ve been waiting for a continuation and hoping that the author gets better since last year TTATT

For those unfamiliar with the manga, Brutal: Confession of a Homicide Investigator or Brutal: Satsujin Keisatsukan no Kokuhaku is kinda like Dexter (the tv show) except the main character is much, much more unhinged, loves the look of despair of his asshole victims and goes all out to making their death karmic and ironic.

Also… he does pottery (badly), his favorite movie is The Exorcist and it’s implied his first love was a man who died before he could kill him XD

It’s super dark and the manga does not shy away from all the gory details and dark themes (when I say the MC’s victims are assholes, it’s an understatement). Seriously, there’s a lot of triggering stuff in this manga that each chapter usually have a warning label. It’s also short with only 19 chapters due to the author’s poor health so… if you wanna try it out, it won’t take too much of your time.

.

Anyway!

I feel like Desmond wouldn’t do what Dan does to his ‘victims’, mostly because the Brotherhood stresses to respect everyone, even the people they kill. The Hidden Blade is meant to deliver swift deaths, prolonging the death of the target as some sort of punishment would be against that ‘tradition’.

Although, to be fair, if we set this up as Desmond having lost a bit (or most) of his sanity after the Solar Flare, it would work.

Or…

This would be a Desmond who joined the police force after leaving the Farm. It’s highly unlikely since Abstergo would be all over him once he delivers the necessary paperwork and the results of his medical checkups but maybe he gets a lucky break, maybe Erudito is actively helping him by changing all of his information before it could get to Abstergo…

Maybe someone in the Calculations is ensuring he stays away from Abstergo’s radar. Weird computer glitches, strangely timed bad luck, accidents leading to data corruption… No one would think that someone is behind it unless they believe that that someone would be a ‘higher being’.

In this scenario, Desmond would see the worst of mankind and how the world as it is right now let some of these monsters get away. Desmond would use both the skills and techniques he learned from his profession and his childhood training in punishing these monsters the way they deserve to be punished.

In either scenario (Desmond becoming unhinged after the Solar Flare or Homicide Investigator!Desmond), Desmond wouldn’t care if they were Templars or not. As long as they have done something ‘bad’ and got away with it, they become his targets. 

But he’d still wear a hood and a mask to hide his identity.

So when Abstergo ‘finds’ footage of him, they assume he’s an Assassin out for revenge and they wouldn’t think that the other non-Templar/Abstergo related disappearance are related until it’s too late.

The Assassins would think he’s a rogue Assassin, most probably a survivor of the Great Purge that has cut all ties with everyone. They don’t necessarily agree with his ‘methods’ but they let him do as he pleases because (1) they have no idea who he is or even how to predict his movements (2) he’s only targeting horrible people so it’s not technically against the Creed, and (3) they need all the help they can get.

(It would be funny if Desmond’s fake identity’s first name is Dexter. I mean… I’d probably go for Derek as usual if I was to write this (big IF) but giving him Dexter as a fake name would be funny)

.

.

.

Hey, nonny.

You know what would be funny?

If Desmond goes to Japan after the Solar Flare to sorta-chill, sorta-relax, sorta-have a vacation and he just starts becoming some sort of vigilante during his time there. And Dan… falls in love with him. Both as the vigilante and as the nice foreigner working as a barista in the cafe near the police station or something. Just imagine a fusion of cafe au and serial killer au with a heavy topping of yandere from Dan and ‘I have really bad choices in love interests and I know it’ from Desmond XD

Canon Eclipse meeting Experiment Lunar after KC stole the traumatised lil' fella

Canon Eclipse probably would halt seeing him but not interact since he knows Lunars aren't something to mess with. If Experiment Lunar is lost, he may guide him back to the daycare and bolt from the homicidal Sun, or have Solar Flare do it.

[chocolix76]

Gonna say my honest feelings about some of the Sun and Moon Show villains.

Bloodmoon, Solar Flare, and Killcode deserved better.

For Bloodmoon, I personally believe that he had barely any time to reach his full potential as a villain. Yes, we knew he was a threat and that he did some pretty awful things, but for the most part, he didn't do much to directly harm Sun and Moon up until the very end (from my knowledge at least). Also, he never had the opportunity to develop as a character. Towards the end, he began to show some awareness that Killcode was using them as a pawn, but he never got to act upon that feeling or at least further elaborate on it.

What also irks me about Bloodmoon was the fact that they died for no good reason. Yeah, I will admit that they were asking to be killed since they were teasing Sun while he was snapping, but where did the Sun snapping arc go? Nowhere. So Bloodmoon's death was pretty much for nothing, except for him to become some hallucination that taunts him, but also borderline gives him therapy at the same time. He also never had the chance to become a better villain or even be redeemed before he was killed. I could go on and on about Bloodmoon but I'll end it there.

Solar Flare on the other hand barely even had the chance to be a character. I will admit, I was on the fence about him at first, but he grew on me and became a character I genuinely enjoyed seeing, even if his entire personality was pretty much protecting Killcode. Poor Solar Flare was written so poorly (in my opinion) that I didn't even know he was considered dead until much later on. He was pretty much created just to die a few weeks later and at that point, I don't even see why he was needed. Other than Eclipse using his body, and Solar Flare giving Moon instructions on how to build a satellite, I don't think there was any substance to his character at all. Justice for Solar Flare.

As for Killcode...I don't even know what to say about him. When the homicide code arc started, Killcode being introduced was not something I expected, nor was it something I was pleasantly surprised about. I feel like the arc could have worked even better without him because...KC was barely even explored in his own arc. He deserved to be the proper villain he was made to be before getting his redemption. Besides, his redemption didn't do much besides have him disappear from the show almost completely and just eliminate him as a threat for Sun and Moon. If he was going to be incorporated into the show, I just wish that he had been more fleshed out as a character.

[tmnt-obsessed-ace]

I got Eclipse Across Dimensions thoughts again so here's how the other tmnt variations get dragged into the mess

First 2003

2012 Raph and a heavily injured Rise Leo end up in the 2003 universe (I want to put that around the time the 2003 boys get their own mystic powers but I STILL havent finished season 1 of that show so I dont know exactly when that is) This os also the scenario I have the least planned out because again I have not finished tmnt 2003

Next is the 2007 movie

After the stone monsters are sent back to their dimension at the end of the movie the portal spits out Rise Donnie, who is two seconds away from full on biting people so the 2007 gang has to reel in this extremely pissed off softshell turtle. Shenanigans ensue

Then the 1987 series

Arguably the one with the least amount of fighting since 2012 Leo knows them. He's been to this dimension before and the 87 boys are happy to see him...until they realize that he is covered in wounds and about five seconds away from sobbing or committing mass homicide, whichever comes first.

And meanwhile while all of this is happening 2012 Donnie is going through his own version of "Same As It Never Was" (aka this poor boy witnessing the Mutant Apocalypse future and then realizing that the mutagen bomb is almost complete. Oof this boy will need so many hugs)

Still dont know how the Mutant Mayhem boys would fit in (because y'know THE MOVIE'S NOT OUT YET)

In a desperate attempt to find the others, both Mikeys go universe hopping using the portal generator. They end up in the Last Ronin universe

I might add the Bayverse turtles but that would mean watching the movies (those movies should've been 2D they should've been 2D why do they look like that?)

This crossover will be fucking massive

(not to mention that multidimensional eclipse will ALSO happen in TMNT: Solar Flare's season five finale but they're staying in their own dimension because I have some kind of sense. Plus I want the Solar Flare boys to stand on their own without the canon versions behind them)

Screaming

[noivoom]

 Okay, after several days of brainstorming and debating with myself, I have finally decided to emerge from The Lurking Pit and share this little (“little”) thing! This AU came about from my love of dysfunctional family tropes as well as my desire for everyone to live (honestly I mostly just wanted to daydream fanfic ideas without having to navigate canon’s minefield of problems, began wondering what an “ideal” situation would look like, and this spawned out of it)

The point of this was to, again, create an “ideal” situation for the gang, with potential for all kinds of Shenanigans™ and Drama™ alike while still keeping everyone as close to their canon selves as possible, as a bit of relief from all the angst :’) (I say “ideal situation,” but that doesn’t mean they haven’t still got issues galore. *cough*SUNNEEDSTHERAPY*cough*) (If, on the off chance anyone is inspired by this and/or wants to make something with this setting, please let me know! I’d LOVE to see it! :D)

I call it- One big UnHappy Family!

TL;DR Sun, Moon, Lunar, Earth, KC, Bloodmoon, and Solar Flare are all alive and well and somehow ended up as the world’s most Complicated™ family. Chaos ensues.

As for how they wound up that way? WELL. I’m gonna start rambling now, please bear with me

It starts with Sun shooting Bloodmoon. Sun didn’t fully know if he really wanted to kill Bloodmoon, was fighting internally to come to a decision one way or another and therefor wasn’t actually aiming when a moment of reflex kicked in, and the barrel went off. And he misses. Well... mostly. Bloodmoon takes a decent amount of the shot, and though it doesn’t kill them, they’re left severely damaged. It’s quite a confronting sight for Sun- while in canon there was nothing left of BM for Sun to really understand the weight of what he just did (at first, anyway), here he’s immediately confronted with another animatronic panicking and in pain as their nanomachines desperately try to rebuild them :’) Nothing like a bit of visual trauma to hit home that your actions have consequences, amirite? Moon investigates the barrel shot and sudden screaming (from both BM and Sun) to find... this. He’d probably have several things in mind to say to Sun about shooting BM, but he’d hold off for now. And thus begins one hell of a domino effect.

While fixing Bloodmoon, it becomes apparent the barrel shot corrupted some of their code. Nothing particularly bad, but oddly enough, it seems to have somehow also curbed their bloodlust. The lack of cravings leave the twins disoriented and kinda lost, but it’s also... almost a relief. Lunar takes advantage of this, introducing them to new things to occupy their time, and wow, who knew they could find entertainment in something other than homicide and appalling crimes against humanity? They’re still Bloodmoon, of course, they still have to be held back from killing people, but that’s not all they wanna do anymore. And food! Now that their bloodlust is out of the way food tastes so much better, there’s so many different flavours and textures and they gotta try everything and whoops, they’ve accidentally found themselves on the world’s weirdest redemption arc. (So, uh, thanks for shooting them after all, Sun...? I guess?)

Meanwhile KC, concerned over Bloodmoon’s wellbeing, convinces Moon to let him watch over them during their recovery. As the twins begin discovering new things that satisfy themselves, KC, trying to be Dad™, joins them. He’s never actually participated in anything that doesn’t involve murder, and much of these activities are uninteresting to him, but something about doing it with his sons... it actually... satisfies something in him, too. (None of them are particularly good at finding non-violent hobbies, mind you, but Lunar, Sun and Moon help out. Mostly to keep them occupied. They have no idea what’s going on, but they much prefer whatever the hell this is to evil plotting.) Eventually Moon relaxes a little when he realises KC intends to stay true to their deal, and occasionally switches off while KC’s out rather than watching him like a hawk. This leads to KC exploring on his own and running into Glamrock Freddy. He panics a little and pretends to be Moon. A parallel of their canon talk happens and oh would you look at that, KC’s accidentally Dad-ed his way into a redemption arc of his own! (No dead Bloodmoon means Sun doesn’t McFreaking Lose It, which means Lunar doesn’t move out and get killed, and also means the magic circle isn’t destroyed, which means Moon doesn’t get stuck in his head and get his memories wiped! :D Huzzah!) (Sun is still in desperate need of therapy though)

Eclipse is, of course, rather indignant at this turn of events. He never like the Blood Twins or KC, but seriously? Just like that?! It’s almost insulting. Not to mention it screws up his plan (not that he’d had a chance to flesh out said plan yet anyway). He continues regardless, taking over Solar Flare’s body to... do something. I’ll admit, I haven’t exactly figured out what his new course of action would be. Regardless, he ends up making his own body and ditches Solar Flare without a second thought. Solar Flare, alone and deeply disturbed over having their body hijacked so easily, is at a loss for what to do when they stumble upon Earth! Or more accurately, she stumbles upon them. She comforts them and they go with her to the Daycare. (I also don’t know if Earth would have already joined the DCA crew or if she just shows up fashionably late with Starbucks Solar Flare. Both are funny; either she shows up as a stranger with another stranger like “yes hello I’m your new sister, also I decided to bring this vaguely traumatised stranger along with me, hope you don’t mind :)” or she goes for a walk and comes back with this stranger like “can we keep them? *puppy eyes*”) Thus, Solar Flare joins the family!

Honestly... despite everyone else getting redeemed/joining the family, I think it’s funniest if Eclipse stays a bad guy. Everyone else is learning about themselves and growing as individuals/family, meanwhile Eclipse is over there being a stubborn, petty, lonely bastard and refusing to acknowledge that the reason he is miserable everywhere he goes is because every time he goes somewhere, he is there. Also he creates the conflict needed for further plot to happen. Also also I don’t think he’d take the option of redemption if it was handed to him on a silver platter accompanied by a ten-page essay on why it’s the best choice for everyone, especially him. (But who knows! I guess it is possible, it would just be a lot of work. He’d have to really want to be better and put the work in. Even then, I imagine he’d probably end up going his own way. It’d be for the best after all the trauma he’s inflicted.)

The FUNNIEST pat of all of this is when Glamrock Freddy visits the Daycare to talk to Sun and Moon about something only to see Sun yelling and chasing Bloodmoon, who’s knocking over and destroying EVERYTHING, Lunar running after them playing the Benny Hill theme, Solar Flare robotically restacking the barrels one pile at a time (seemingly oblivious to the fact that Bloodmoon knocks them over again as soon as they turn their back, creating an endless cycle they don’t seem to question), Earth calling out for everyone to please not hurt themselves, and Moon just... sitting there, rubbing his temples. “... Hey Freddy,” Moon says, not looking up. “... What the heck is going on?” “Family bonding.” “Family- where the heck did all these people even come from?!” “It’s a long story.”

If you’ve read all this, thank you so much for hearing me out <3 I’ll admit, most of my thought processes behind this boil down to “I just think it’s neat” and “because I think it’s funny”. This is supposed to be just for fun, after all. Please tell me what you think! There’s SO MUCH more to this, from evolving family dynamics to specific character development and even Monty, this post is all just the basic set-up of how the gang got to where they are. I have SO MANY more thoughts about this setting, it’s a disaster and a half and I’d love to discuss it please give me an excuse to ramble more

Currently Listening To: "Solar Flare Homicide" by Emmure

[madcatdaderpydrawer-blog]

(girl ((gender neutral)) help I've exceeded the post limit) I'm imaging how Blaze would be if he were to find TF while he's carrying Solar Flare's developing AI. Nothing really changes except for after he saves Nee-Nee he skips threats and goes straight to strangling TF Moon, Monty, and Sun. He's angry and emotional and on a warpath, his siblings don't dare try to stop him. Nee-Nee is his son now and he must Protecc.

He’s especially violent because of his semi not really but sorta pregnancy so he just jumps immediately to homicidal rage while the others try to distract Nee-nee from what’s soon going to be a blood bath. After he’s done committing mass murder he takes his new son and picks him up like a stuffed animal because this is his now

Emmure - “Solar Flare Homicide” [x]

[snowe-zolynn-rogers]

AU where Solar Flare and Eclipse actually get along and share the body decently without any murder attempts, and Eclipse is taking a nap when Sun shows up, and Solar Flare is internally panicking that whole conversation and starts crying and begging for Eclipse to wake up and help when Sun decides to try killing him, too? 🦇

Like Eclipse knows his child is sentient and needed to get out of the lab to escape and get them both safer. But couldn't make his own body or KC would be mad upon finding out he did so Solar Flare offers to be a temporary vessel while Eclipse is making himself a body in another bunker so he can take his son and just up and leave KC alone.

Eclipse is sleeping after a two day stretch of finishing his body in the other bunker when Sun comes in and Solar Flare tries to keep his dad safe, but also trying to wake him to get advice on what exactly to say to the homicidal sun man who invaded Flare's grandfather's bunker.

Eclipse realizes Sun finally caught up to them soon after waking up and teleports them to the other bunker they've been visiting for Eclipse's body and they transfer him over and go on the run together.

imagine if at a christmas truce party the ghosts discover that danny has a second obsession of space

Wrote a fic~ *does a little dance*

.

"Here's your invitation to the truce party," said Skulker, dropping the letter by Danny's head, "and here's the duty list. Pick something." He shoved a piece of paper into Danny's face.

"You know," said Danny, testing the rope Skulker had tied him with, "you get a lot better at chasing me when you're doing it for non-murder purposes."

Skulker scowled, but Danny knew better than to take his apparent facial expression as a sign of his true emotions. After all, the face Danny could see wasn't really Skulker's. It was a mask. One the tiny green jellybean inside could manipulate as he pleased.

"What do you mean, 'duty list,' anyway?" Danny blew the paper off his nose.

"It's a list. Of duties. For people who want to attend the party. You can't possibly imagine that one ghost does it all on their own, do you?"

"I don't know. Some living people are really into the holidays. Wouldn't surprise me if there was someone over in the GZ Obsessing."

"There are," said Skulker flatly. "But going to those parties is risky."

"Oh. Yeah. I guess that makes sense. So, is this, like, a potluck deal, or white elephant, or do I have to come set up, or what?"

"Read the list, whelp!"

"I would," said Danny, "if you held it far enough away for me to see what was written on it. "My eyes don't focus that close."

Grumbling, Skulker adjusted his position.

A lot of the things on the list were already checked off. The rest looked dangerous (fighting the Krampus), time consuming (holly acquisition, with a stupidly high number of branches listed next to it), expensive (providing new holiday table settings), confusing (Danny didn't know what a 'consoda' was, or why he would fetch offerings from it), or simply extraordinarily unappealing (after party cleanup). Except for one.

One that caught Danny's eye because of a very specific word that was included.

"Why's the star all by itself?" asked Danny.

"Because the star is important," said Skulker. "Adding the star to the tree is what starts off the real celebration. A star needs to be impressive. Dramatic! Not one of those little dinky tinsel things you can find at human stores."

Part of Danny knew he shouldn't- But when had he ever listened to that part of himself?

Actually, that wasn't really fair. He listened, otherwise he'd be fully dead instead of just half.

Still.

(The idea of making a star made his skin feel sparkly and fuzzy, like his whole body was half an inch from the surface of freshly poured soda, but all over.)

"I'll take it," he said.

"Humf," said Skulker. "Don't screw up, or you'll be in for a beating as soon as the truce is over." He made a mark by the name and started to fly off.

"Hey! Aren't you going to untie me?"

"Nah."

.

"He's late," said Desiree, sharply, glaring at Skulker as if he had any control over what the whelp did or did not do.

She wasn't the only one.

"He's not late yet," defended Skulker.

"You shouldn't have given him the star as a choice," complained Technus, his voice squaking like a poorly connected computer speaker. "You should have just told him what he'd have to do. Something that wouldn't ruin the party. He's a teenager! Teenagers are easily distracted."

"I didn't know you were a teen, techie," drawled Spectra, who really shouldn't have been at the party at all, seeing as she wasn't, and never had been, invited. Skulker was hoping someone would find a way to throw her and her little minion out before midnight.

"It's TECHNUS, MASTER OF TECHNOLOGY, CONTROLLER OF ALL THINGS ELECTRONIC AND BEEPING."

"I am sure Sir Phantom is on his way," said Princess Dora, softly, ignoring Technus's continuing rant with the ease of long practice. She would not be here the whole evening. Her kingdom had its own, separate celebrations, but they wouldn't start for well over half a human day. "He is a very responsible person, and he was speaking to me about stars just earlier this month." She frowned, slightly, swirling the darkly luminous wine in her glass. "That is, I think he was talking about stars. The conversation was somewhat difficult for me to follow."

"Oh, no," said Desiree, putting one hand delicately over a smile.

"What?" growled Skulker.

"It always bothered me a little, you see, but I hadn't realized quite why until just now." She was barely even trying to hide her delight. "The second time I fought him, it was during a meteor shower."

"So?" asked Amorpho.

"He was rather cross with me during the fight. At the time, I thought it was because he was missing that girl's party, or because of the whole memory wiping thing, but in retrospect..."

"Just spit it out already," said Skulker.

"I do believe you gave the task of making the tree star to a ghost Obsessed with outer space."

Inside the suit, Skulker's true hands slip off his controls for just a moment. "Oh, Ancients," he groaned.

"We're not getting a star this year, are we?" asked Ember.

Phantom chose that moment to barrel through the door. "Sorry!" he exclaimed, looking and sounding more like a little kid than Skulker had ever witnessed. "Am I late? No, I'm not. Never mind. I'm not sorry. What do you think?"

He held out the... thing in his hands for the assembled ghosts to view. It was... It was definitely a star. A round blue star. Complete with solar flares and sunspots. Animated flares and sunspots.

"How the hell?" whispered Walker in the background, despite the fact that he and his pink prison really had no room to talk.

"Is it no good?" asked Phantom, managing to shift his weight even though he was floating. "I turned the brightness way down so that everyone could see the details, but I think I could turn it back up again without too much trouble." He blinked up at the other ghosts, and Skulker noticed with some unease that his pupils were currently shaped like crescent moons. "I mean, the other one exploded, but I think I've got it, now."

All of the ghosts slid back, just slightly. Not that they were afraid of explosions, but, well, being cautious didn't hurt.

"Er," said Dora, "what is it, exactly?"

"A star! A blue giant, specifically. Well, a model of one, anyway, but I think it's a good model. I mean, it's a blue giant right now. I've got it set up so that it'll go through the whole life cycle of a massive star. Or, not the whole life cycle, because that would include the nebula, but the life cycle from this point? It'll change color and expand as the night goes on and it uses up its 'hydrogen'- I've scaled the expansion, though, don't worry, it won't take over- and then the core will collapse and the outer layers will be ejected, and- BOOM!- supernova!"

"Ghost child," said Technus, in a more strangled than usual voice, "are you telling us that's a bomb?"

"No, it's a star," said Phantom, blankly. On closer inspection, the crescents in his eyes were not the only modification to Phantom's appearance. He had pale green and silver stars scattered liberally across his nose and cheeks, and similar shapes in the black of his costume.

In the background, Desiree was dying of laughter.

"Don't you think a supernova might be... dangerous?"

"Oh, a real one, sure. But I tested one before I brought this, and all it did to me was singe my eyebrows off, and I was standing really close."

"Whelp," said Skulker, searching for some reason to reject Phantom's 'contribution,' "how is that even supposed to stay on the tree? It's just a ball."

"Oh, it'll float wherever I tell it to, don't worry, I've tested it!"

.

It perhaps said something about ghostly parties that the sudden detonation of the tree topper several hours later, the subsequent glee of the supposed superhero in attendance when the room was filled with star-shaped glitter and confetti, and the attempted homicide on the part of several glitter-unfriendly ghosts was not the most exciting series of events to occur that night.

Hubble finds best evidence for elusive mid-sized black hole

Astronomers have found the best evidence for the perpetrator of a cosmic homicide: a black hole of an elusive class known as "intermediate-mass," which betrayed its existence by tearing apart a wayward star that passed too close.

Weighing in at about 50,000 times the mass of our Sun, the black hole is smaller than the supermassive black holes (at millions or billions of solar masses) that lie at the cores of large galaxies, but larger than stellar-mass black holes formed by the collapse of a massive star.

These so-called intermediate-mass black holes (IMBHs) are a long-sought "missing link" in black hole evolution. Though there have been a few other IMBH candidates, researchers consider these new observations the strongest evidence yet for mid-sized black holes in the universe.

It took the combined power of two X-ray observatories and the keen vision of NASA's Hubble Space Telescope to nail down the cosmic beast.

"Intermediate-mass black holes are very elusive objects, and so it is critical to carefully consider and rule out alternative explanations for each candidate. That is what Hubble has allowed us to do for our candidate," said Dacheng Lin of the University of New Hampshire, principal investigator of the study. The results are published on March 31, 2020, in The Astrophysical Journal Letters.

The story of the discovery reads like a Sherlock Holmes story, involving the meticulous step-by-step case-building necessary to catch the culprit.

Lin and his team used Hubble to follow up on leads from NASA's Chandra X-ray Observatory and ESA's (the European Space Agency) X-ray Multi-Mirror Mission (XMM-Newton). In 2006 these satellites detected a powerful flare of X-rays, but they could not determine whether it originated from inside or outside of our galaxy. Researchers attributed it to a star being torn apart after coming too close to a gravitationally powerful compact object, like a black hole.

Surprisingly, the X-ray source, named 3XMM J215022.4?055108, was not located in a galaxy's center, where massive black holes normally would reside. This raised hopes that an IMBH was the culprit, but first another possible source of the X-ray flare had to be ruled out: a neutron star in our own Milky Way galaxy, cooling off after being heated to a very high temperature. Neutron stars are the crushed remnants of an exploded star.

Hubble was pointed at the X-ray source to resolve its precise location. Deep, high-resolution imaging provides strong evidence that the X-rays emanated not from an isolated source in our galaxy, but instead in a distant, dense star cluster on the outskirts of another galaxy -- just the type of place astronomers expected to find an IMBH. Previous Hubble research has shown that the mass of a black hole in the center of a galaxy is proportional to that host galaxy's central bulge. In other words, the more massive the galaxy, the more massive its black hole. Therefore, the star cluster that is home to 3XMM J215022.4?055108 may be the stripped-down core of a lower-mass dwarf galaxy that has been gravitationally and tidally disrupted by its close interactions with its current larger galaxy host.

IMBHs have been particularly difficult to find because they are smaller and less active than supermassive black holes; they do not have readily available sources of fuel, nor as strong a gravitational pull to draw stars and other cosmic material which would produce telltale X-ray glows. Astronomers essentially have to catch an IMBH red-handed in the act of gobbling up a star. Lin and his colleagues combed through the XMM-Newton data archive, searching hundreds of thousands of observations to find one IMBH candidate.

The X-ray glow from the shredded star allowed astronomers to estimate the black hole's mass of 50,000 solar masses. The mass of the IMBH was estimated based on both X-ray luminosity and the spectral shape. "This is much more reliable than using X-ray luminosity alone as typically done before for previous IMBH candidates," said Lin. "The reason why we can use the spectral fits to estimate the IMBH mass for our object is that its spectral evolution showed that it has been in the thermal spectral state, a state commonly seen and well understood in accreting stellar-mass black holes."

This object isn't the first to be considered a likely candidate for an intermediate-mass black hole. In 2009 Hubble teamed up with NASA's Swift observatory and ESA's XMM-Newton to identify what is interpreted as an IMBH, called HLX-1, located towards the edge of the galaxy ESO 243-49. It too is in the center of a young, massive cluster of blue stars that may be a stripped-down dwarf galaxy core. The X-rays come from a hot accretion disk around the black hole. "The main difference is that our object is tearing a star apart, providing strong evidence that it is a massive black hole, instead of a stellar-mass black hole as people often worry about for previous candidates including HLX-1," Lin said.

Finding this IMBH opens the door to the possibility of many more lurking undetected in the dark, waiting to be given away by a star passing too close. Lin plans to continue his meticulous detective work, using the methods his team has proved successful. Many questions remain to be answered. Does a supermassive black hole grow from an IMBH? How do IMBHs themselves form? Are dense star clusters their favored home?
