When the Black Hole Was Born: Astronomers Identify the Epoch of the First Fast Growth of Black Holes
ScienceDaily (Dec. 28, 2010) — Most galaxies in the universe, including our own Milky Way, harbor super-massive black holes varying in mass from about one million to about 10 billion times the size of our sun. To find them, astronomers look for the enormous amount of radiation emitted by gas which falls into such objects during the times that the black holes are “active,” i.e., accreting matter. This gas “infall” into massive black holes is believed to be the means by which black holes grow.
