Super-massive black hole mass scaling relations

, , and .
(Nov 5, 2014)

Abstract

Using black hole masses which span 10^5 to 10^(10) solar masses, the distribution of galaxies in the (host spheroid stellar mass)-(black hole mass) diagram is shown to be strongly bent. While the core-Sersic galaxies follow a near-linear relation, having a mean M\_(bh)/M\_(sph) mass ratio of \~0.5\%, the Sersic galaxies follow a near-quadratic relation: M\_bh\~M\_sph^(2.22+\-0.58). This is not due to offset pseudobulges, but is instead an expected result arising from the long-known bend in the M\_(sph)-sigma relation and the log-linear M\_(bh)-sigma relation.
