Photometry and Photometric Redshift catalogs for the Lockman Hole Deep Field
S. Fotopoulou, M. Salvato, G. Hasinger +8
We present broad band photometry and photometric redshifts for 187611 sources located in ~0.5deg^2 in the Lockman Hole area. The catalog includes 389 X-ray detected sources identif…
On the Lx-L6micron ratio as a diagnostic for Compton-thick AGN
I. Georgantopoulos, E. Rovilos, A. Akylas +6
As the mid-IR luminosity represents a good isotropic proxy of the AGN power, a low X-ray to mid-IR luminosity ratio is often claimed to be a reliable indicator for selecting Compto…
X-ray observations of highly obscured 9.7 micron sources: an efficient method for selecting Compton-thick AGN ?
I. Georgantopoulos, K. M. Dasyra, E. Rovilos +8
Spitzer/IRS has revealed many sources with very deep Si features at 9.7micron (tau>1). We set out to investigate whether a strong Si absorption feature is a good indicator for the…
Optical and infrared properties of active galactic nuclei in the Lockman Hole
E. Rovilos, S. Fotopoulou, M. Salvato +4
We present the observed-frame optical, near- and mid-infrared properties of X-ray selected AGN in the Lockman Hole. Using a likelihood ratio method on optical, near-infrared or mid…
