| Description | POX 52 is a Narrow-Line Seyfert 1 galaxy with extreme and unusual properties. Its black hole mass, estimated from the optical spectrum of the AGN, is only virgul10^5 solar masses; its host galaxy is a dwarf elliptical with a velocity dispersion of only 36+/-5 km/s; and it is radiating at L/L_Edd virgul 1. POX 52 offers a unique opportunity to study black hole accretion at high accretion rates in a mass range that has barely been explored previously. We request 100 ksec of EPIC-pn observations of this unique AGN in order to characterize its X-ray spectrum and absorption, to search for Fe K line emission, to study its variability properties, and to search for quasi-periodic oscillations with the aim of better constraining the black hole mass. |

| 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. |
