Scientific paper

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 z0 will allow, along with the X-ray surveys at higher redshift, to better understand the AGN evolution.
