We propose to observe for 25ks the late-type galaxies NGC3367 and NGC 4536,which are both optically classified as normal galaxies but have been recentlydiscovered by Spitzer to host AGN. The exquisite sensitivity of XMM will beexploited to: 1) model in detail the X-ray spectrum to estimate the bolometricluminosity of the nuclear region; 2)Search for an FeK alpha line, whose energy,profile, and strength are a function of the geometry and the physical state ofreprocessing medium 3) study the X-ray variability and put constraints on theblack hole mass. The proposed pilot study will open up opportunities to studythe characteristics of the largely unexplored low black hole mass regime and thelow mass end of the M_{rm BH} - sigma_star relation.

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.
