The Clustering of AGN Using Photometric Redshifts Elias Koulouridis Antonis Georgakakis National Observatory of Athens

Previous Results A. Coil et al projected cross- correlation function (w p ) in AEGIS of 132 X-ray AGNs with 4669 galaxies from DEEP2 survey.

Limitations Deep2 is a unique catalogue of spectroscopic redshifts. Small number of X-ray AGN in AEGIS/DEEP2. Other studies are not possible, like the study of the Luminosity dependent evolution of the AGN clustering.

Limitations Log(L bol /L o ) Hopkins et al Bias b(L)

Probability Density Function (PDF) of Photometric Redshifts Binned distribution with dz=0.04 from z=0 up to z=6 Our redshift bin is ±300 h -1 Mpc = 5 bins in the PDF

Samples 110 X-ray detected AGN galaxies in AEGIS/CFHTLS ~21000 PDFs ~10 6 random galaxies
