| Abstract | We propose to obtain new XMM light curves of 5 AGN with reverberation-basedblack hole mass from the Lick AGN Monitoring Project (LAMP) to investigate howtheir variability properties scale with black hole mass and Eddington ratio.These 5 sources are among the AGN with the smallest measured black hole masses(M_BH = 1E6-1E7 M_Sun), making them an important bridge between the variabilityproperties of supermassive and stellar mass black holes. Moreover, we will usethe XMM observations to calibrate X-ray variability as a mass estimator at lowmasses for AGN, which can be used to search for the seeds of supermassive blackholes in nearby bulge less dwarf galaxies. |

| 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. |
