Energy outflows from quasars on the scale of what Arav’s team observed have been predicted for some time by theorists, but have never been recorded by researchers. The existence of such emissions may answer a question that has intrigued astrophysicists for some time. While theoretical models of the universe tend to approximate what researchers observe, one major difference has persevered: Theoretical models tend to overestimate the mass of black holes relative to the rest of the galaxy. If quasars are ejecting energy at the rate observed by Arav’s team, this could explain where that mass goes. But the theory rests on the notion that such emissions are fairly common, and the team’s discovery is the first such emission researchers have observed. As a result, Arav and his team now want to find more powerful quasar emissions to cement the idea. –LA Times
Astronomers have found a quasar that's more than five times more powerful than any previously seen. Quasars are mega-bright geysers of matter and energy powered by super-massive black holes at the centers of young galaxies.
