... 2009 April 19 . The View Near a Black Hole . ... Explanation: In the center of a swirling whirlpool of hot gas is likely a beast that has never been seen directly: a black hole . ... The gas surrounding GRO J1655-40, for example, has been found to display an unusual flickering at a rate of 450 times a second. Given a previous mass estimate for the central object of seven times the mass of our Sun , the rate of the fast flickering can be explained by a black hole that is rotating very rapidly. ...

Observations over the last decade indicate black-holes likely resided at the heart of most if not all galaxies. The correlation between the masses of these compact nuclear sources and their host galaxy is poorly understood and likely plays an important role in the formation and evolution, of at least the most massive systems, due to AGN feedback. ... I will give a brief summary of the reverberation mapping technique and describe the important role SkyMapper photometry can play in this program. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
