Earlier this year, the Dark Energy Spectroscopic Instrument (DESI) completed observations that mapped 47 million galaxies across 11 billion light-years, allowing astronomers to better evaluate the ...

A study based on 47 million galaxies found that the cosmic web retains patterns on enormous scales, which could force a reevaluation of a pillar of cosmology.

A new JCAP study tests an “emulator” to reconstruct the large-scale structure of the cosmos If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together ...

The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space Telescope (JWST) in an area of the sky called COSMOS ...

Gamma-ray bursts (GRBs) are the most energetic events ever observed in the universe. These powerful outbursts can shine a quintillion (10 18) times brighter than the sun. Since they were first ...

The largest known structure in the Universe may be even larger than the large we thought it was. A re-examination of the distribution of powerful space explosions suggests that the Hercules-Corona ...

The large-scale structure of the Universe arises from the gravitational amplification of primordial fluctuations, producing a cosmic web of galaxies, filaments, clusters and voids. At sufficiently ...

New cosmic census based on five years of data opens a powerful new window into the large-scale structure of the universe ...

Modern cosmology rests on a simple assumption: if we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known as the cosmological ...

Primordial non-Gaussianity refers to deviations from a perfect Gaussian distribution in the initial density fluctuations generated during cosmic inflation. These subtle departures carry information ...
