New research suggests that ultraviolet light may have cleared gas and dust in early galaxies, allowing them to appear brighter ...

New simulations show that Lyman-alpha radiation from young stars can blast gas and dust out of early galaxies, clearing the ...

Theoretical physicists have determined how a phase-space-dependent Gauss–Bonnet coupling alters the post-inflationary reheating duration and temperature while satisfying cosmological constraints.

A quantitative assessment reveals that turbulence-like power spectra in postinflationary condensate fragmentation are strictly interval-dependent and hold across only a ...

JWST and ALMA observations have revealed two actively accreting supermassive black holes separated by about 1.5 kiloparsecs in a gas-rich ...

A new theoretical study proposes that globular clusters could have formed around thousand-solar-mass primordial black holes created at the QCD ...

Researchers at the Center for Astrophysics | Harvard & Smithsonian have created Lumina, the largest cosmological radiation-hydrodynamics simulation ever built, ...

A quantitative comparison of 12 dark-matter models found that primordial black holes can be as natural as some particle candidates, ...

The Lumina simulation, run on one of the world's most powerful supercomputers, tracks dark matter, galaxies, stars, and radiation across ...

UCLA-led simulations show that extremely dense stellar systems in the early universe may have produced frequent stellar collisions, repeated mergers ...
