In a recent study, published in the journal Nature, a group of scientists from the Rochester Institute of Technology report on their study of the rotating winds the rise up above the accretion disks surrounding supermassive black holes in distant galaxies. and the galaxies they inhabit better and better. In fact, it now looks like the powerful winds that blow out of these monsters can have a significant effect on the galaxies they inhabit, helping determine their growth.

With millions of times the mass of the Sun, supermassive black holes pull strongly at the material in their host galaxy. Just like water going down a drain, this material backs up into a swirling accretion disk. The material heats up, and blazes with radiation visible clear across the Universe - this is a quasar.
