The process of galaxy merging reshapes cosmic structure by driving dramatic changes in the distribution and state of interstellar gas, thereby governing the rates and locations of star formation.

Researchers led by a Rutgers University-New Brunswick astrophysicist, who looked deeply into space at a period known as "Cosmic Noon," about 2 billion to 3 billion years after the Big Bang, have found ...

Peak star formation took place during cosmic noon, between 2–3 billion years after the Big Bang. The star formation rate (SFR ...

These three galaxy images from the AEGIS survey show a range of galaxy types: a disk-like spiral galaxy (top), a cloud-like elliptical galaxy (middle), and an irregular galaxy resulting from a ...

Astronomers have discovered a vast, dense cluster of massive galaxies just 1 billion years after the Big Bang, each forming stars at an intense rate from collapsing clouds of dust. Reported in ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

Inside-out growth and stellar migration in the Milky Way: Inside the star-forming disc (within ~12 kpc), abundant cold gas fuels continuous star formation, producing young stars. Beyond this break ...

In the intriguing realm of star-forming galaxies, the key factor isn't the total amount of gas but rather its strategic distribution within the galaxy. Researchers at the International Centre for ...

Abstract : Weighing in at 1042 kilograms and measuring 1021 meters across, galaxies are perhaps the most awe-inspiring objects known to mankind. They are also the only places in an otherwise dark and ...

Distant galaxies that abruptly stopped making stars have puzzled astronomers for years. About 9 billion years ago, during one ...

The formation and evolution of galaxies are governed by the processes that assemble their mass and regulate the conversion of gas into stars. Over cosmic history, galaxies grow through the accretion ...

In an unprecedented leap forward in our understanding of the universe’s origins, NASA’s James Webb Space Telescope (JWST) has potentially identified the earliest galaxy ever observed. This galaxy ...
