Barnes Iii, John Kormendy, Christopher Sneden and Amy Dove Forestell. A team of astronomers including Karl Gebhardt and graduate student Jeremy Murphy of The University of Texas at Austin have discovered the most massive black holes to date – two monsters weighing as much as 10 billion Suns and threatening to consume anything, even light, within a region five times the size of our solar system. They consist of a 'halo' of dark matter typically containing hundreds, sometimes thousands, of galaxies. Karl Gebhardt1 Dept.
