Scientific paper

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 FeKalpha 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_{ m BH}-sigma_star relation.
