| Abstract | We will study a candidate intermediate-mass black hole (IMBH) we have recentlydiscovered in the halo of the nearby (d~135 Mpc) elliptical galaxy NGC 6099. Thesource had a soft (thermal) X-ray spectrum with a luminosity Lx ~ 5e42 erg/s ina 2012 XMM-Newton observation, up from Lx ~ 7e40 erg/s seen in a (short) 2009Chandra observation. With a new XMM-Newton observation, we will explore itsspectral evolution or transient behaviour and constrain the origin of thethermal emission and the mass range of the accreting object. If confirmed as anoff-nuclear IMBH, its X-ray properties will help us focus our search for thiselusive class of object, relics of dwarf satellite accretion during major galaxyassembly. |

| 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. |
