Description There is growing evidence that a fraction of starburst galaxies host heavily obscured, "elusive" active nuclei which are not identified by optical spectroscopy. This finding suggests that the fraction of AGNs in the local universe is higher than previously estimated. We propose a snapshot XMM survey of 10 starburst galaxies characterized by nuclear radio cores, suspected to host hidden AGNs. The main goals are: 1) determine the fraction of galaxies hosting "elusive" AGN; 2) determine the true distribution of absorbing column densities in AGNs; 3) obtain a larger sample of "elusive" AGNs to be studied in detail to better understand their nature; 4) constraining the true AGN density at z=0 will allow, along with the X-ray surveys at higher redshift, to better understand the AGN evolution.

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.
