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…
A Quantum Bubble Could End Reality as We Know It. Here’s Why It (Probably) Won’t
Physicists have many delightful theories about how our universe might end, including one that suggests it isn’t in…
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…
Astronomers hear a mysterious ‘hum’ across the universe; one explanation begins with strange dark stars 13 billion years ago
Astronomers may have found a new way to investigate one of the biggest mysteries in cosmic history: how…
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…
Astronomers Discover a Brand-New Type of Object: Part Black Hole, Part Star
At the cosmic dawn, the universe was sprinkled with giant black holes—monstrosities so huge that scientists are still…
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…
