| X-Raying Black Holes September 16, 2005 Strange as it sounds, black holes are among the brightest objects in the universe. As their gravity tears apart anything that strays too close, the doomed material heats up to unbelieveable temperatures and releases tremendous energy in the form of X-Rays. This lecture will show how those X-rays are used to identify black holes, measure their mass, and understand how they slowly consume their companion stars. |
