| Description | 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 recently discovered by Spitzer to host AGN. The exquisite sensitivity of XMM will be exploited to: 1) model in detail the X-ray spectrum to estimate the bolometric luminosity 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 of reprocessing medium 3) study the X-ray variability and put constraints on the black hole mass. The proposed pilot study will open up opportunities to study the characteristics of the largely unexplored low black hole mass regime and the low mass end of the M_{rm BH} - sigma_star relation. |

| 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. |
