WebThe black hole in the galaxy M87 has a mass of about 3 billion solar masses. Let us assume that most of the mass flowed into the black hole through an accretion disk that … WebAbstract. The radio:X-ray correlation for hard and quiescent state black hole X-ray binaries is critically investigated in this paper. New observations of known sources, along with newly discovered ones (since 2003), have resulted in an increasingly large number of outliers lying well outside the scatter about the quoted best-fit relation. dallas l barnes
