Projected density of galaxies within 0.5 Mpc and with | z_AGN−z_galaxy | ≤ 0.2 from the obscured and unobscured AGN (shaded and solid line histograms, respectively). The dot-long dash line histogram shows the galaxy counts obtained in a control galaxy field. Long dash line histogram correspond to the distribution of galaxies in the field of Lyman-break galaxies with spectral type obtained from a star-burst galaxy. We introduce an artificial shift in the dot-long dash histogram for clarity.
