Recent observations imply that at redshift zero, most of the nuclear activity must reside in low mass galaxies, mostly late-type spirals and dwarf ellipticals. We initiated a Chandra survey and an archival program to search for low-level nuclear activity in a sample of nearby low-mass galaxies. We propose XMM observations of three galaxies in each of which a nuclear X-ray source was detected with Chandra. X-ray spectra and optical to X-ray spectral energy distributions obtained with XMM will secure the identification of the X-ray sources as AGNs. We will also study the typical characteristics of low-luminosity AGNs. This will maximize the scientific returns of our Chandra survey, with important consequences toward understanding the formation and co-evolution of SBHs and galaxies.
