How Early Galaxies Shaped the Universe!  #sciencefather #universe #researcher 

Early massive galaxy formation had a profound impact on the cosmic microwave background (CMB) 🌌, the faint afterglow of the Big Bang. As these colossal galaxies formed in the young universe 🌠, their intense gravitational fields and energetic processes—like supernovae 💥 and active galactic nuclei powered by supermassive black holes 🕳️—began to interact with the surrounding environment. This activity influenced the CMB through phenomena such as the Sunyaev-Zel’dovich effect 🔥❄️, where high-energy electrons scattered the CMB photons, subtly altering their energy. Moreover, the clustering of massive galaxies distorted the CMB through gravitational lensing 🔭, bending the paths of photons as they traveled across the cosmos. These imprints help cosmologists 🧠🛰️ understand the structure and evolution of the universe, offering clues about dark matter, dark energy, and the timing of galaxy formation across cosmic history. 🕰️🌍✨

Euclid Spacecraft Reveals Dark Universe

A treasure trove of data from the Euclid spacecraft, including significant contributions from UK scientists, has unveiled the largest images of the Universe ever captured from space. The release marks a milestone in the quest to understand dark matter and dark energy.  

Unveiling the Dark Universe

A significant breakthrough in space exploration has emerged from the European Space Agency's Euclid mission. Launched in July 2023, the mission aims to map the ‘dark Universe’ by observing two billion galaxies to create a comprehensive 3D map. UK scientists have played a pivotal role in this mission, contributing to the release of the largest space images ever taken.  

The Significance of the Euclid Mission

The Euclid mission is dedicated to uncovering the mysteries of dark matter and dark energy, which comprise most of the Universe but remain poorly understood. The data released, stemming from only 24 hours of observations, offers a glimpse into the immense potential of Euclid in studying the cosmos.   Dr. Caroline Harper, Head of Space Science at the UK Space Agency, emphasized the mission's importance: "A key part of our purpose as a space agency is to understand more about the Universe, what it’s made of and how it works. The Euclid mission epitomizes this quest."   Contributions from UK Scientists UK scientists have been integral to the Euclid mission, contributing significantly to its early results. Among the notable contributions is a paper by Professor Mark Cropper from UCL Mullard Space Science Laboratory. Over 16 years, he led the development of the VIS optical camera, one of the largest ever sent into space, supported by £20 million of UK Space Agency funding.   Professor Mark Cropper remarked: "These are the largest images of the Universe ever taken from space, covering large swathes of the sky in fine detail. They demonstrate Euclid’s wide-ranging potential."  

Exploring the Perseus Cluster

Another groundbreaking paper from Professor Nina Hatch at the University of Nottingham examines the Perseus Cluster, a group of galaxies 240 million light-years away. This cluster is crucial for understanding dark matter, as its formation relies on the presence of this elusive substance.   Professor Nina Hatch highlighted a surprising discovery: "Euclid’s images of the Perseus Cluster revealed a faint glow between the galaxies, known as intracluster light. This light can help us map dark matter if we understand where the intracluster stars came from."   Technological Marvel: The VIS Optical Camera The VIS optical camera is a technological marvel, requiring exquisite precision and stability to achieve Euclid's core aims. The UK’s contribution to this instrument underscores its commitment to pioneering space science. Feature Description VIS Optical Camera One of the largest cameras sent to space, developed over 16 years UK Space Agency Funding Supported by £20 million of funding Key Applications Discovering new planets, studying dark matter, mapping galaxy clusters Technological Specifications Requires high stability and precise conditions Imaging Capability Produces largest images of the Universe ever taken from space   The Role of the UK in Data Processing The UK’s involvement extends beyond instrument development. It plays a significant role in the Euclid Science Ground Segment, processing data from the telescope into science-ready products. A consortium of UK universities, led by the University of Edinburgh, provides critical data processing pipelines.   Professor Andy Taylor from the University of Edinburgh noted: "These new images from Euclid are stunning. They demonstrate both the image quality and the huge area of the sky seen by Euclid in each observation."  

Teledyne e2v, based in Chelmsford, provided the telescope’s Charged Couple Device detectors. Photo by Teledyne e2v. Gov.uk.   Industrial Contributions and International Collaboration Teledyne e2v, based in Chelmsford, provided the telescope’s Charged Couple Device detectors, crucial for capturing high-resolution images. This collaboration highlights the synergy between industry and academia in advancing space science.   Antonio Spatola, Director of Business Development and Sales at Teledyne e2v, expressed pride in their contribution: "We are privileged to contribute enabling technology to this important science mission."   A Step Forward in Cosmic Understanding The Euclid mission represents a remarkable achievement in space exploration and a significant step forward in our understanding of the dark Universe. UK scientists and institutions have demonstrated excellence in contributing to this mission, showcasing the nation's leadership in space science and technology. As the Euclid mission continues, the data and images it provides will be instrumental in answering fundamental questions about the Universe's composition and evolution. The collaboration and dedication of scientists and engineers across the globe underscore the importance of international efforts in uncovering the secrets of the cosmos.   Sources: THX News & UK Space Agency.

JAMES WEBB DESCOBRE SEGREDO PRECIOSO ESCONDIDO EM AGLOMERADO DE GALÁXIAS

SPACE TODAY NO TEATRO: "MARTE, NOSSO PRÓXIMO DESTINO?" 13 DE ABRIL | 16:00 | TEATRO GAZETA - SP INGRESSOS: https://bileto.sympla.com.br/event/103209 FAÇA A SUA PÓS NA ACADEMY SPACE: https://academyspace.com.br/astronomia O estudo investiga o fenômeno do cooling flow no Phoenix Cluster (z = 0.597), onde o meio intraaglomerado quente (ICM) deveria esfriar rapidamente e alimentar a formação estelar na galáxia central. Contudo, na maioria dos aglomerados, esse resfriamento esperado não é observado devido ao feedback energético de buracos negros supermassivos. O Phoenix Cluster se destaca por apresentar um forte fluxo de resfriamento, associado a uma alta taxa de formação estelar e um buraco negro em rápida acreção. Utilizando o Telescópio Espacial James Webb (JWST) e seu instrumento MIRI/MRS, os pesquisadores mapearam a emissão da linha [Ne VI] λ7.652 µm, permitindo visualizar gás a temperaturas intermediárias (~10⁵,⁵ K). Os dados revelaram uma emissão extensa e espacialmente coincidente com regiões de resfriamento do ICM, gases mais frios e formação estelar ativa. A análise sugere que um episódio recente de resfriamento acelerado aumentou a taxa de resfriamento para 5.000–23.000 M⊙ por ano, um valor muito maior que os estimados anteriormente. Os resultados mostram que o gás resfriado está localizado atrás de uma bolha de plasma gerada por feedback do buraco negro central, o que sugere que a turbulência causada pelo jato do buraco negro pode promover o resfriamento em vez de apenas inibi-lo. Esse estudo representa o primeiro mapeamento detalhado do fluxo de resfriamento em todas as fases de temperatura dentro de um núcleo de aglomerado, fornecendo novas evidências sobre o papel do feedback de buracos negros na evolução de galáxias massivas. fonte: https://arxiv.org/abs/2502.08619 #JAMESWEBB #GALAXYCLUSTER #UNIVERSE

This rich galaxy cluster, catalogued as CL0024+17, is allowing astronomers to probe the distribution of dark matter in space. The blue streaks near the center of the image are the smeared images of very distant galaxies that are not part of the cluster. The distant galaxies appear distorted because their light is being bent and magnified by the powerful gravity of CL0024+17, an effect called gravitational lensing. Dark matter cannot be seen because it does not shine or reflect light. Astronomers can only detect its influence by how its gravity affects light. By mapping the distorted light created by gravitational lensing, astronomers can trace how dark matter is distributed in the cluster. While mapping the dark matter, astronomers found a dark-matter ring near the cluster's center. The ring's discovery is among the strongest evidence that dark matter exists. The Hubble observations were taken in November 2004 by the Advanced Camera for Surveys.
