Description 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.

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.
