cds-question@unistra.fractive-galactic-nucleiquasarsvisible-astronomysloan-photometryWe present photometry of the large-scale environments of a sample of 12 broad line active galactic nuclei (AGNs) with 0.06<z<0.37 from deep images in the Sloan Digital Sky Survey u, g, r, and i filters taken with the 90Prime prime focus camera on the Steward Observatory Bok Telescope. We measure galaxy clustering around these AGNs using two standard techniques: correlation amplitude (B_gq_) and the two point correlation function. We find average correlation amplitudes for the 10 radio-quiet objects in the sample equal to (9+/-18, 144+/-114, -39+/-56, 295+/-260)Mpc^1.77^ in (u, g, r, i), all consistent with the expectation from galaxy clustering. Using a ratio of the galaxy-quasar cross-correlation function to the galaxy autocorrelation function, we calculate the relative bias of galaxies and AGNs, b_gq_. The bias in the u band, b_gq_=3.08+/-0.51 is larger compared to that calculated in the other bands, but it does not correlate with AGN luminosity, black hole mass, or AGN activity via the luminosity of the [OIII] emission line. Thus ongoing nuclear accretion activity is not reflected in the large scale environments from ~10h^-1^kpc to ~0.5h^-1^Mpc and may indicate a non-merger mode of AGN activity and/or a significant delay between galaxy mergers and nuclear activity in this sample of mostly radio-quiet quasars.2015ApJ...800...93Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/800/93CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/258 : Quasars and Active Galactic Nuclei (13th Ed.)
