The Search for Hidden Black Holes, a.k.a.
Many astronomers think so, but no one has ever been able to prove it.
Now, using Chandra, a group of 10 English and one French astronomer have published observations of an object that appears to be an optical Clark Kent galaxy with a camouflaged Superman, a.k.a. This model is an extension of an earlier model used to explain galaxies that show unusual energetic activity in their central regions. Visit our archives . Type 2 AGNs show evidence of less energetic activity in the form of scattered light and gas moving at moderate speeds, some radio activity in the form of jets, and no low energy X rays. The AGN unified model, developed by astronomers Robert Antonucci, of the University of California, Santa Barbara, and Joseph Miller of the University of California, Santa Cruz, proposed that Type 1 and Type 2 AGNs could have a common explanation a donut-shaped veil of gas and dust around a central black hole.
