New black holes

[alokmohan]

he massive, growing black holes, discovered by NASA's Spitzer and Chandra space telescopes, represent a large fraction of a long-sought missing population. Their discovery implies there were hundreds of millions of additional black holes growing in our young universe, more than doubling the total amount known at that distance. <br /><br />"Active, supermassive black holes were everywhere in the early universe," said Mark Dickinson of the National Optical Astronomy Observatory in Tucson, Ariz. and co-author. "We had seen the tip of the iceberg before in our search for these objects. Now, we can see the iceberg itself."
