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 diet.

The discovery was made as part of a program to detect supermassive black holes, millions or billions of times more massive than the Sun, that are not at the centers of galaxies.
