A huge ULX bubble in NGC 5585
Abstract
Accreting black holes release their power through radiation and/or jets. We have discovered an ultraluminous X-ray source (ULX) in the nearby galaxy NGC 5585, surrounded by a large (diameter ~300 pc) ionized nebula. We propose a joint XMM- Newton and HST study of this source. With XMM-Newton, we will determine the radiative power of the ULX, its spectral and time variability properties, and constrain its mass. With HST, we will image the nebula, determine whether it is a jet-inflated ULX bubble, measure its kinetic power and source age, and search for an optical counterpart to the black hole.
