Death Stars, Weird Galaxies, and a
Quasar-spangled Universe: ...
A quasar turns on when gas and stars fall into a black hole. As the black hole
feeds, it produces the enormous amounts of energy coming from the quasar. So a
quasar is thought to be the bright, active center of a galaxy. Seeing far into the
past ...

Evolution of the
Quasar Population at High Redshift
The quasar luminosity function (QLF) is thus of particular importance in
understanding quasar formation and evolution and exploring physical models of
quasars. It has been shown that quasar activity and the formation processes of
galaxies ...
The fact that quasars often change significantly in brightness over the course of a
single day indicates to scientists something of surpassing importance: A quasar
must be no larger than about one light-day, or the distance that light travels ...
