OVV quasarAn optically violent variable quasar (often abbreviated as OVV quasar) is a type of highly variable quasar. It is a subtype of blazar that consists of a few rare, bright radio galaxies, whose visible light output can change by 50% in a day.

• that may explain why some quasars are surrounded by galaxies: the galaxy didn「t form the quasar; rather the quasar pulled in the galaxy.

  这也许可以解释为什么有些类星体会被星系包围着：星系并没有形成类星体，相反，是类星体把星系吸引过来的。
