Twelve billion years ago, long before our sun was even a cloud of dust, a young galaxy flared with a light that shouldn’t ...
A research team has investigated quasar variability by tracking optical to mid-infrared (MIR) wavelengths of variability ...
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.
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 ...
Astronomers have found the oldest-known X-ray quasar in the universe — and its properties align exactly with predictions for a new class of distant objects made by Yale astronomer Priyamvada Natarajan ...
Theoretical predictions have been confirmed with the discovery of an outflow of molecular gas from a quasar when the Universe was less than a billion years old. Theoretical predictions have been ...
