摘要：
Galaxies in the environments of 69 0.2 < z < 0.7, UBR-selected active galactic nuclei (AGNs) have been imaged to By applying photometric redshifts and color selection criteria to the galaxy B(J) similar to 23.5. catalog, the AGN-galaxy cross-correlation function has been measured as a function of galaxy type. The spatial cross-correlation of AGNs with red (early-type) galaxies is comparable to the autocorrelation function of elliptical galaxies at low redshift. In contrast, the cross-correlation of AGNs with blue (late-type) galaxies is weak and has been detected with low signifcance. Since blue galaxies dominate B(J) similar to 23.5 galaxy catalogs, the cross-correlation of UBR-selected AGNs with all galaxies is weak at intermediate redshifts.
