Member Spotlight (Feb. 24, 2020) on Dr. Junhan Kim: Dr. Junhan Kim AIAA LA-LV Member Robert A. Millikan Postdoctoral Scholar in Physics California Institute of Technology (Caltech) Junhan is an experimental astrophysicist and has been working as a postdoctoral researcher at Caltech since September 2019. He finished Ph.D. in the Department of Astronomy and Steward Observatory at the University of Arizona in Tucson. As a graduate student, he worked on the Event Horizon Telescope (EHT; https://eventhorizontelescope.org) project to study the supermassive black holes. The EHT project is an experiment that announced its first results last year: imaging the nuclear black hole in the galaxy M87. The EHT combines a global network of widely separated radio telescopes to simulate a much larger aperture, to make images at the highest angular resolution ever achieved. He developed a receiver for the South Pole Telescope (SPT; https://pole.uchicago.edu), and the EHT became a true Earth-sized virtual telescope with the successful addition of the SPT to the array. For this work, he has traveled to the South Pole, Antarctica, five times since 2014. He is broadening the research area from the black hole study to observational cosmology with several new projects at Caltech. He has been fascinated by astronomy since high school when he took pictures of astronomical objects as a hobby. He was curious about the nature of the objects he photographed and enjoyed expanding knowledge on the subject by reading college-level textbooks. Also, he found electric circuits and robots to be very interesting as well. Therefore, he studied both electrical engineering and astronomy at Seoul National University in South Korea before entering graduate school in the US. During the undergraduate years, he realized that astronomy had expanded its research frontiers with the help of leading-edge instruments and techniques. Then he decided to take part in the development and application of technologies to achieve still-unsolved problems in astrophysics. He very much enjoys sharing his scientific experiences with others. He had a chance to share his graduate work with AIAA LA-LV section members as soon as he moved to California last Fall (November 9, “Event Horizon Telescope: Studying Black holes from the South Pole”). Recently, he wrote a popular science book, “Exploring the Universe from the South Pole,” in Korean with his friend Dr. Jae Hwan Kang (Stanford University). In the book, the authors share their experience at the South Pole and introduce the astronomers’ efforts to take pictures of the black holes and search for the signal from the early universe.

#Blackhole adalah bagian dari ruang waktu yang merupakan gravitasi paling kuat, bahkan cahaya tidak bisa kabur. Teori relativitas umum memprediksi bahwa butuh massa besar untuk menciptakan sebuah lubang hitam yang berada di ruang waktu. Di sekitar lubang hitam ada permukaan yang di sebut #horizon peristiwa. Objek ini disebut "hitam" karena menyerap apapun yang berada disekitarnya dan tidak dapat kembali lagi, bahkan cahaya. Secara teoretis, lubang hitam dapat memliki ukuran apa pun, dari mikroskopik sampai ke ukuran alam raya yang dapat diamati. Teori medan kuantum dalam ruang-waktu melengkung memprediksi bahwa horizon peristiwa memancarkan radiasi disekitarnya dengan suhu yang terbatas. Suhu ini berbanding terbalik dengan massa lubang hitam, sehingga sulit untuk diamati lubang hitam bermassa bintang atau lebih. Lubang hitam terbagi menjadi 2: lubang hitam dan lubang hitam supermasif yang seringkali ada di pusat suatu galaksi. Lubang hitam supermasif di dalam inti galaksi elips superraksasa Messier 87 di konstelasi #Virgo. Massanya diperkirakan mencapai miliaran kali lipat massa Matahari, 7.22+0.34 −0.40×109 M☉, pada tahun 2016.[1] Foto ini diambil secara langsung oleh #eventhorizontelescope Telescope dan dirilis tanggal 10 April 2019.

Do You Know that First ever black hole image released? Scientists have unveiled an image of a#supermassive #blackhole, known as #M87, which is at the centre of our neighbouring Virgo A galaxy. This #BlackHole image released by Event Horizon Telescope team in world first time . Until now, every image of a black hole you have ever seen has been an artist's impression The image is the result of a seven year project linking telescopes all over the world to create 'a dish the size of the planet' The fact the image matches so closely to#predictions is a confirmation of #Einstein's theory of general relativity. Before all new information i want You to 1st know about What is a black hole? A black hole is a region of space from which nothing, not even light, can escape.Despite the name, they are not empty but instead consist of a huge amount of matter packed #densely into a small area, giving it an immense #GravitationalPull. There is a region of space beyond the black hole called the event horizon. This is a "point of no return", beyond which it is impossible to escape the gravitational effects of the black hole. Details have been published today in #AstrophysicalJournal Letters. The image shows an intensely bright "ring of fire", as Prof Heino Falcke, of #RadboudUniversity in the#Netherlands, describes it, surrounding a perfectly circular dark hole. The bright halo is caused by#superheated gas falling into the hole. The light is brighter than all the billions of other #stars in the#galaxy combined - which is why it can be seen at such distance from #Earth. The edge of the dark circle at the centre is the point at which the gas enters the #blackhole, which is an object that has such a large #gravitationalpull, not even light can escape. It measures 40 billion km across - three million times the size of the Earth - and has been described by#scientists as "a monster". The black hole is 500 million trillion km away and was #photographed by a network of eight telescopes across the world. "It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exists. It is an absolute monster, the heavyweight champion of black holes in the Universe." According to Prof Falcke"It is remarkable that the image we #observe is so similar to that which we obtain from our #theoretical calculations. So far, it looks like #Einstein is correct once again." But having the first image will enable #researchersto learn more about these #mysterious objects. They will be keen to look out for ways in which the black hole departs from what's expected in #physics. No-one really knows how the #brightring around the hole is created. Even more intriguing is the question of what happens when an object falls into a black hole.

The first ever image of a black hole taken by @ehtelescope. More precisely, it's the image of the matter around the black hole interacting, heating up and releasing radiation before falling behind the event horizon, from which nothing can escape. This picture would hence not be possible without the many body interactions between matter and light! . . . #ehtelescope #eht #blackhole #eventhorizontelescope #eventhorizon #outreach #astronomy #manybodyphysics #plasma #red #orange #photography https://www.instagram.com/p/BwGcRtPFCCf/?utm_source=ig_tumblr_share&igshid=1qaj06gwq7kva

First ever photographic proof of a Super Massive Black Hole. Located in Galaxy M87, it is 6.5 billion times the mass of our sun....and it's pretty f#%'n cool. #eventhorizontelescope #blackhole #supermassiveblackhole #nerdgasm #spaceistheplace (at Black Hole - The Mystery of Universe) https://www.instagram.com/howgregory/p/BwGTCZ7p_Ej/?utm_source=ig_tumblr_share&igshid=vqfqkjs61d08
