Black hole on a diet creates a 'changing look' quasar
New Haven CT (SPX) Jan 24, 2015
Yale University astronomers have identified the first "changing look" quasar, a gleaming object in deep space that appears to have its own dimmer switch. The discovery may offer a glimpse into the life story of the universe's great beacons. Quasars are massive, luminous objects that draw their energy from black holes. Until now, scientists have been unable to study both the bright and dim phases of a quasar in a single source. As described in an upcoming edition of The Astrophysical Journal, ... read more
