Galaxy Clustering around VLA-COSMOS sources

The Voronoi Tessellation Approach (VTA; see SmolčIć et al. 2007, and references therein) has been used to quantify galaxy clustering around radio sources detected at 1.4 GHz in the COSMOS field (Schinnerer et al. 2007, SmolčIć et al. 2008). Overdensities have been searched for in a projected area on the sky encompassing a well defined redshift bin, and extending 10 Mpc times 10 Mpc in the (ra,dec) plane. The half-width of the redshift bin for each radio source has been taken to be 3 times the typical photometric redshift error (0.007(1+z) for i<22.5, and 0.0334(1+z) for i>22.5; see Fig. 7 in Ilbert et al. 2008).
The VTA results for each radio source are here.
