Galaxy clusters, often referred to as the “big cities” of the universe, are populated by giant elliptical galaxies that have stopped forming stars and completed their growth. Despite extensive research, the exact mechanism behind this shutdown of star formation remains uncertain. In a groundbreakin...
theory-galaxiesclustersUsing semi-analytic approach, we present an estimate of the properties of thelargest virialized dark halos in the present universe for three different scenarios ofstructure formation: SCDM, u039bCDM and OCDM models. The resulting virial mass andtemperature increase from the ...
We've known for a while about the large-scale structure of the Universe. Galaxies reside in filaments hundreds of millions of light-years long, on a backbone of dark matter. And, where those filaments meet, there are galaxy clusters. Between them are massive voids, ...
Galaxy clusters, known as the largest self-gravitating objects in the universe, are home to a vast expanse of high-temperature gas. This gas emits brilliant X-rays, making these clusters visible. When these colossal clusters merge, it culminates in an astronomical event of unmatched magnitude,...
Magnifying The Universe: Interactive Journey from the Smallest Particles to the Largest Galaxies By Dr. Winston Ewert Published: Jun 16, 2022 Updated: Jul 28, 2023 Zoom in and out for fun, or stop and read, the choice is yours. We take you from the smallest known things in the universe...
Instead, the large star-filled objects clump together in a web, and this is the large-scale structure of the universe, according to ESO. Scientists working with the Very Large Telescope found that the rotation of the quasars is parallel to the large-scale structures where the galaxies are ...
close to describing the objects astronomers are discovering in deep space. There are definitely no words to describe their latest find, dubbed the BOSS Great Wall, which is a supercluster of galaxies over 1 billion light years across, making it the largest structure observed in the universe so ...
a cosmologist at the University of Portsmouth in England who was not involved in the study, toNew Scientist. Hence, asthe universe expands, “some of those galaxies may drift apart from each other instead of collapsing in on themselves, in which ca...
The star that transforms into a red supergiant does so at a cost. It loses a large percentage of its mass out to space. As a result, while red supergiants are counted as the largest stars in the universe, they are not the most massive because they lose mass as they age, even as th...
Many scientists think that there are super-massive black holes at the center of galaxies."This special black hole, which is about 30 billion times the mass of our sun, is one of the biggest ever discovered.* It is an exciting discovery," said James Nightingale, a scientist at Durham ...
