N2 - We present the two-point correlation function (2PCF) of narrow-line active galactic nuclei (AGNs) selected within the First Data Release of the Sloan Digital Sky Survey. Using a sample of 13,605 AGNs in the redshift range 0.055 < z < 0.2, we find that the AGN autocorrelation function is consistent with the observed galaxy autocorrelation function on scales from 0.2 to greater than 100 h-1 Mpc. The AGN hosts trace an intermediate population of galaxies and are not detected in either the bluest (youngest) disk-dominated galaxies or many of the reddest (oldest) galaxies. We show that the AGN 2PCF is dependent on the luminosity of the narrow [O III] emission line (L [O III]), with low L[O III] AGNs having a higher clustering amplitude than high L[O III] AGNs. This is consistent with lower activity AGNs residing in more massive galaxies than higher activity AGNs, and L[O III] providing a good indicator of the fueling rate. Using a model relating halo mass to black hole mass in cosmological simulations, we show that AGNs hosted by ∼1012 M⊙ dark matter halos have a 2PCF that matches that of the observed sample. This mass scale implies a mean black hole mass for the sample of MBH ∼ 108 M⊙.
