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.
