Why X-ray--Selected AGN Appear Optically Dull
J. R. Rigby, G. H. Rieke, J. L. Donley +2
We investigate why half of X-ray--selected active galactic nuclei (AGN) in deep surveys lack signs of accretion in their optical spectra. The majority of these ``optically--dull''…

Unveiling a Population of X-ray Non-Detected AGN
J. L. Donley, G. H. Rieke, J. R. Rigby +1
We define a sample of 27 radio-excess AGN in the Chandra Deep Field North by selecting galaxies that do not obey the radio/infrared correlation for radio-quiet AGN and star-forming…

Why Optically--Faint AGN Are Faint: The Spitzer Perspective
J. R. Rigby, G. H. Rieke, P. G. Perez-Gonzalez +5
Optically--faint X-ray sources (those with f_X/f_R > 10) constitute about 20% of X-ray sources in deep surveys, and are potentially highly obscured and/or at high redshift. Their f…
