The Iron line (stacked) emission properties of Chandra surveys sources
Abstract
We exploit deep Chandra data in the CDF-S (4Ms), CDF-N (2Ms), E-CDF-S (250 ks) COSMOS (160 ks) and AEGIS (800 ks) fields to perform source stacking analyses of iron K lines in integrated X-ray spectra of the ~190 brightest X-ray sources, as a function of luminosity, redshift, and absorption column density. The combined Chandra datasets substantially improve the statistics for the low-redshift AGN population (z<1) and provide new sources detected mostly at z>1. The average rest-frame properties of AGN can be studied, allowing a full characterization of the line intensity and line profile. The available multi-wavelength data allow us to study Iron-line properties also as a function of the optical properties of the AGN host galaxies (stellar masses, star formation rates), therefore putting the production of iron within the more general AGN-host galaxies co-evolution framework.
