The Nature of Optically Dull Active Galactic Nuclei in COSMOS (2009)
Trump, Jonathan R., Impey, Chris D., Taniguchi, Yoshi, Brusa, Marcella, Civano, Francesca, Elvis, Martin, ...
We present infrared, optical, and X-ray data of 48 X-ray bright, optically dull active galactic nuclei (AGNs) in the COSMOS field. These objects exhibit the X-ray luminosity of an AGN but lack broad...

X-ray spectral analysis of optically faint sources in the Chandra Deep Fields (2005)
Civano, Francesca, Comastri, Andrea, Brusa, Marcella
We present the results of a detailed spectral analysis of optically faint hard X-ray sources in the Chandra deep fields selected on the basis of their high X-ray to optical flux ratio (X/O). The...
A broad iron K alpha line at z=1.146 (2004)
Comastri, Andrea, Brusa, Marcella, Civano, Francesca
We report the discovery of a strong iron K alpha line in the hard X-ray selected source CXOJ 123716.7+621733 in the Chandra Deep Field North survey at z=1.146. The analysis is made possible by the...
