Cross-correlation function for AGNs and their control galaxies. Left panels, Upper panel: 2PCCF of cAGN (black) and its control star-forming (cSF^c) and quiescent galaxies (cQ^c). Lower panel: 2PCCF ratio of cAGN to cSF^c (blue) and cAGN to cQ^c (red). The horizontal dashed line (red) indicates the theoretical halo bias (Tinker et al. 2010) ratios between cAGN and cQ^c with halo mass derived by M1. The vertical dotted line (grey) indicates the virial radius of the host halo of cAGN derived by M2. Middle panels: same as the left panels, but for cAGN_σ* and their control galaxies, cSF and cQ. Right panels, Upper panel: 2PCCF for cAGN and its control galaxies (cG^c), tAGN and its control galaxies (tG^c). Lower panel: 2PCCF ratio of cAGN to cG^c and tAGN to tG^c. See Sect. 2.1 for the sample construction.
