The clustering of X-ray selected AGN at z=0.1

The clustering properties of moderate luminosity ($L_X = \rm 10^{41} - 10^{44} \, erg \,s^{-1}$) X-ray selected AGN at $z\approx0.1$ are explored. X-ray sources in the redshift interval $0.03dark matter haloes that host X-ray AGN at $z\approx0.1$ is $\approx 10^{13} \,h ^{-1} \, M_{\sun}$. Comparison with studies at higher redshift shows that this mass scale is characteristic of moderate luminosity X-ray AGN out to $z\approx 1$. Splitting the AGN sample by rest-frame color shows that X-ray sources in red hosts are more clustered than those associated with blue galaxies, in agreement with results at $z\approx1$. We also find that the host galaxies of X-ray AGN have lower stellar masses compared to the typical central galaxy of a $\approx 10^{13} \,h ^{-1} \, M_{\sun}$ dark matter halo. AGN hosts either have experienced less stellar mass growth compared to the average central galaxy of a $\approx 10^{13} \,h ^{-1} \, M_{\sun}$ halo or a fraction of them are associated with satellite galaxies.
