Why super massive black holes consume less material than expected
Amherst MA (SPX) Sep 03, 2013 – Using NASA’s super-sensitive Chandra X-ray space telescope, a team of astronomers led by Q. Daniel Wang at the University of Massachusetts Amherst has solved a long-standing mystery about why most super massive black holes (SMBH) at the centers of galaxies have such a low accretion rate-that is, they swallow very little of the cosmic gases available and instead act as if they are on a severe die … more

Ultracold Big Bang experiment successfully simulates evolution of early universe
Chicago IL (SPX) Sep 03, 2013 – Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the University of Chicago. “This is the first time an experiment like this has simulated the evolution of structure in the early universe,” said Cheng Chin, professor in physics. Chin and his associates rep … more

NASA’s Chandra catches our galaxy’s giant black hole rejecting food
Huntsville AL (SPX) Sep 03, 2013 – Astronomers using NASA’s Chandra X-ray Observatory have taken a major step in explaining why material around the giant black hole at the center of the Milky Way Galaxy is extraordinarily faint in X-rays. This discovery holds important implications for understanding black holes. New Chandra images of Sagittarius A* (Sgr A*), which is located about 26,000 light-years from Earth, indicate tha … more
