Title: Probing the Limits of Nuclear Activity with the COSMOS Survey

The Cosmological Evolution Survey (COSMOS) is centered on the largest contiguous region of the sky ever imaged by HST. It was motivated by the study of galaxy evolution and morphology but the combination of depth, breadth and extensive multiwavelength data makes it the best region in the sky for a comprehensive study of AGN. This talk will concentrate on AGN selected by X-ray emission, and the search for AGN with low black hole mass, low accretion rates, and high levels of obscuration that removes them from optical surveys.
