Abstract
Galaxies in the environments of 69 0.2<z<0.7 UBR selected AGN have been imaged to Bj~23.5. By applying photometric redshifts and color selection criteria to the galaxy catalogue, the AGN-galaxy cross-correlation function has been measured as a function of galaxy type. The spatial cross-correlation of AGN with red (early-type) galaxies is comparable to the autocorrelation function of elliptical galaxies at low redshift. In contrast, the cross-correlation of AGN with blue (late-type) galaxies is weak and has been detected with low significance. As blue galaxies dominate Bj~23.5 galaxy catalogues, the cross-correlation of UBR selected AGN with all galaxies is weak at intermediate redshifts.
