ScienceDaily (July 27, 2011) The flow of hot gas toward a black hole has been clearly imaged for the first time in X-rays.

The observations from NASA's Chandra X-ray Observatory will help tackle two of the most fundamental problems in modern astrophysics: understanding how black holes grow and how matter behaves in their intense gravity.

ScienceDaily (July 1, 2010) For decades, X-ray astronomers have studied the complex behavior of binary systems pairing a normal star with a black hole.
In these systems, gas from the normal star streams toward the black hole and forms a disk around it. Friction within the disk heats the gas to millions of degrees -- hot enough to produce X-rays.
At the disk's inner edge, near the black hole, strong magnetic fields eject some of the gas into dual, oppositely directed jets that blast outward at about half the speed of light.
