The Chandra COSMOS Legacy Survey: Compton Thick AGN at high redshift

G. Lanzuisi, F. Civano, S. Marchesi +8

The existence of a large population of Compton thick (CT, ) AGN is a key ingredient of most Cosmic X-ray background synthesis models. However, direct identif…

The Chandra COSMOS-Legacy survey: Source X-ray spectral properties

S. Marchesi, G. Lanzuisi, F. Civano +14

We present the X-ray spectral analysis of the 1855 extragalactic sources in the Chandra COSMOS-Legacy survey catalog having more than 30 net counts in the 0.5-7 keV band. 38% of th…
