New observations reveal that the relationship between ultraviolet and X-ray light in quasars has changed over billions of ...

A team of researchers led by York University Associate Professor Patrick Hall has discovered some strange behaviour occurring in distant galaxies, observing several cases of gas that is “falling” into ...

A new international study suggests that the structure of matter surrounding these black holes has changed over billions of years, calling into question a rule that has guided quasar research for ...

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 ...

Astronomers using the Hubble Space Telescope and other observatories have discovered a pair of gravitationally-bound quasars inside two merging galaxies. Quasars are active and luminous types of ...

Quasars, the luminous beacons at the centers of distant galaxies, have puzzled astronomers for decades with their dramatic brightness variations. Recent observations suggest that these celestial ...

A team of astrophysicists say quasars, some of the most brilliant phenomena in the universe, are likely caused by collisions between galaxies. Quasars are a type of active galactic nuclei; they lurk ...

Astrophysicists have developed a new method for pinpointing the whereabouts of extremely rare extragalactic objects. They hope their technique for finding 'changing-look quasars' will take scientists ...
