Early metal-enriched baryon cycling before the midpoint of cosmic reionization
Observations and data reduction The data analysed in this work were obtained as part of the JWST Cycle…
Overmassive black holes and little red dots naturally form in simulations
Our cosmological initial conditions are based on the simulation Phi-4096 of ref. 51. In this work, a dark-matter-only N-body…
Extended components of little red dots in the rest-frame optical
Furtak, L. J. et al. JWST UNCOVER: extremely red and compact object at zphot = 7.6 triply imaged…
Cosmic plasma was supposed to rule out dark photons. Simulations say otherwise
A major limit on dark photon dark matter may be far weaker because early-universe plasma stops absorbing energy…
Vigorous turbulence driven by quasar-mode feedback in a cluster core
The X-Ray Imaging and Spectroscopy Mission (XRISM)1 is the successor to the Hitomi X-ray observatory2, which ceased operations…
Dark matter may be naturally tuned to a hidden fifth dimension
Dark matter appears to hold galaxies together, yet it has never shown itself directly. A new theory suggests…
New study reveals how dark matter formed shortly after the Big Bang
Dark matter may not have needed a calm, cold start to help build the universe. For decades, that…
Hubble has spotted ‘impossible’ light in deep space, and scientists are trying to explain where it came from
Astronomers have detected light from a tiny but powerful galaxy that existed when the universe was still emerging…
A new window on neutrino astronomy at cosmological distances – Nature
A new window on neutrino astronomy at cosmological distances NatureScientists expected a black hole but found a neutrino factory…
Scientists use Einstein’s equations to reveal what came before the Big Bang
Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far…
Astronomers Trace Elusive High-Energy Neutrino to Star-Forming Galaxy in Early Universe
JCMT0402-0424, a dusty starburst galaxy around 11 billion light-years away, is the strongest candidate yet for the source…
