Researchers from the University of Arizona have recently discovered the most distant quasar to date. This finding allows researchers to answer how black holes can possibly grow. Quasars contain ...

A newly identified quasar shows sustained growth beyond the Eddington limit, prompting new examination of accretion physics, radiation trapping and jet activity in early supermassive black holes.

A research team has investigated quasar variability by tracking optical to mid-infrared (MIR) wavelengths of variability ...

Plenty of groups have been theorizing about primordial black holes (PBHs) recently. That is in part because of their candidacy as a potential source of dark matter. But, if they existed, they also had ...
