Treasure hunting in archive data reveals clues about black holes' diet
Garching, Germany (SPX) Jul 28, 2015
Using archival data from the Sloan Digital Sky Survey, as well as from the XMM-Newton and Chandra X-ray telescopes, a team of astronomers at the Max Planck Institute for Extraterrestrial Physics have discovered a gigantic black hole, which is probably destroying and devouring a big star in its vicinity. With a mass of 100 million times more than our Sun, this is the largest black hole caught in this act so far. The results of this study are published in this month's issue of the Monthly Notices of ... read more
