Accreting black holes release their power through radiation and/or jets. We havediscovered an ultraluminous X-ray source (ULX) in the nearby galaxy NGC 5585,surrounded by a large (diameter virgul300 pc) ionized nebula. We propose a joint XMM-Newton and HST study of this source. With XMM-Newton, we will determine theradiative power of the ULX, its spectral and time variability properties, andconstrain its mass. With HST, we will image the nebula, determine whether it isa jet-inflated ULX bubble, measure its kinetic power and source age, and searchfor an optical counterpart to the black hole.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
