| Description | We are currently in an exciting era where large populations of 1e4-1e6 Msun intermediate black holes are being recovered in the nuclei of low-mass galaxies, which are informing our understanding on the growth of supermassive black holes. However, we still lack observational constraints on possible nuclear black holes in the virgul1000 Msun range, save for a handful of candidates. We identified a 3000-4000 Msun intermediate mass black hole candidate from a Chandra observation of a late-type spiral galaxy, on account of a soft and luminous (near-Eddington) X-ray spectrum. Here, we propose an EPIC XMM-Newton spectrum (with nearly 20 times more counts) to confirm/refute our current intermediate mass black hole interpretation. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
