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 ...

As you might imagine, mapping the universe on the largest of scales and tracing threads of the cosmic web is no mean feat. To do so, you'd need to take observational evidence and combine it with ...

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 ...

Scientists at Rutgers and collaborators have traced the invisible dark matter scaffolding of the universe using over 100,000 Lyman-alpha emitting galaxies. By studying how these galaxies clustered ...

"There are more questions than answers at this point." Dark energy could have an accomplice that helps it slow the growth of large cosmic structures, such as vast superclusters made up of clusters of ...

A Rutgers-led team of scientists has uncovered evidence of how galaxies expand by tracing the invisible scaffolding of the universe created by a mysterious substance known as dark matter. "Analyzing ...

When telescopes capture light from the most distant sources, astronomers are gaining a glimpse of the Universe in its infancy: the finite speed of light implies that, the farther away a cosmic source ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

Nowadays, the dark of night is interspersed with the light of stars. But before the stars were born, did light shine at the beginning of the universe? The short answer is "no." But the long answer ...

A new emulator is tackling the near-impossible task of mapping the universe's large-scale structure without sacrificing intricate details. As you might imagine, mapping the universe on the largest of ...

If you think a galaxy is big, compare it to the size of the universe: it's just a tiny dot which, together with a huge number of other tiny dots, forms clusters that aggregate into superclusters, ...
