The dependence of the X-ray AGN clustering on the properties of the host galaxy

We study the clustering dependence of X-ray active galactic nuclei (AGN) and normal galaxies on the stellar mass (M_⋆), star formation rate (SFR), and specific star formation rate (sSFR) of the (host) galaxy. Towards this end, we use 407 X-ray AGN from the XMM-XXL survey (∼ 25 deg² in the North) and {∼ }45 000 galaxies in the VIPERS field (W1: ∼16 deg²). We match the AGN and galaxy samples to have the same M_⋆, SFR, and redshift distributions. Based on our results, the two populations live in dark matter haloes with similar mass (log M / (M_{⊙} h^{-1})≈ 12.8) and have similar dependence on the galaxy properties. Specifically, our measurements show a positive dependence of the AGN and galaxy clustering on M_⋆ and a negative dependence on SFR and sSFR. We also find that the X-ray clustering is independent of the location of the host galaxy above or below the star-forming main sequence.
