Identifying high redshift AGNs using X-ray hardness
J. X. Wang, S. Malhotra, J. E. Rhoads +1
The X-ray color (hardness ratio) of optically undetected X-ray sources can be used to distinguish obscured active galactic nuclei (AGNs) at low and intermediate redshift from viabl…

The X-Ray Derived Cosmological Star Formation History and the Galaxy X-Ray Luminosity Functions in the Chandra Deep Fields North and South
Colin Norman, Andrew Ptak, Ann Hornschemeier +15
The cosmological star formation rate in the combined Chandra Deep Fields North and South is derived from our X-Ray Luminosity Function for Galaxies in these Deep Fields. Mild evolu…

Tracing the large scale structure in the Chandra Deep Field South
R. Gilli, A. Cimatti, E. Daddi +16
We report the discovery of large scale structures of X-ray sources in the 1Msec observation of the Chandra Deep Field South. Two main structures appear as narrow (Delta_z < 0.02) s…
