Description


We present results from a statistical analysis of 173 bright radio-quiet active galactic nuclei (AGNs) selected from the Chandra Deep Field-North and Chandra Deep Field-South surveys (hereafter, CDFs) in the redshift range of 0.1<~<~4. We find that the X-ray power-law photon index ({Gamma}) of radio-quiet AGNs is correlated with their 2-10keV rest-frame X-ray luminosity (LX) at the >99.5% confidence level in two redshift bins: 0.3~<z~<0.96, and 1.5~<z~<3.3 and is slightly less significant in the redshift bin 0.96~<z~<1.5.
