Definitive Measurements of a Supermassive Black Hole and Its Surrounding Mass

  • Linda Dressel (a1)

Abstract

A discrete thin rotating emission-line disk is ideal for determining the mass of a supermassive black hole in the nucleus of a galaxy. One can use high resolution imaging in combination with a matrix of spatially resolved velocity measurements to confirm the simple geometry and kinematics of the disk. If the disk remains bright and orderly beyond the sphere of influence of the black hole, with motion driven predominantly by gravitational force, one can also measure the density of the surrounding matter in the nucleus. This is being done for the bright Liner galaxy NGC 3998.
