Record-Breaking Fast Radio Burst from Early Universe Traced to Tiny, Star-Forming Galaxy
This fast radio burst, designated FRB 20240304B, is the most distant ever detected, having traveled more than 10…
Reduced incidence of little red dots at z < 3 based on number density and halo mass evolution
Labbé, I. et al. A population of red candidate massive galaxies 600 Myr after the Big Bang. Nature…
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…
Mysterious ‘Little Red Dots’ Could Be Tiny Galaxies with Giant Black Holes at Their Hearts
The mysterious objects spotted in the early Universe may not be isolated points of light after all. A…
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…
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…
Where did the universe’s oldest star clusters come from? A new study has an answer |
For decades, astronomers have searched for the birthplace of globular clusters, the dense spherical collections of stars that…
Hubble Peers into 13-Billion-Year-Old Globular Cluster
Astronomers using the NASA/ESA Hubble Space Telescope have captured this vivid image of NGC 6426, an ancient globular…
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…
