AGN-Galaxy Clustering with the Panoramic Deep Fields

Astrophysics 2007-05-23 v1

Abstract

The AGN-galaxy cross-correlation function of radio-quiet AGN and radio galaxies has been measured with the Panoramic Deep Fields. Colour selection criteria and photometric redshifts have been used to significantly increase the signal-to-noise of the angular cross-correlation function. Radio-quiet AGN environments are comparable to the environments of early-type galaxies at low redshift. The radio galaxy-galaxy spatial cross-correlation function is very strong though large variations are observed from field-to-field. These variations appear to be caused by large-scale-structure on scales comparable to the 5 degree field-of-view. The distribution and spatial cross-correlation function of radio galaxies and clusters in the Panoramic Deep Fields is consistent with these objects tracing the same structures at z<0.7. No evidence is found for evolution of the AGN-galaxy spatial cross-correlation function across the redshift range observed.
