AbstractWe analyze a sample of 30,000 nearby obscured AGNs with SDSS and WISE. We use a “pair-matching” technique to subtract the host 4.6μm contribution, with the aid of SDSS data. By combining Seyferts with local SDSS quasars, we show that the [Oiii] and the intrinsic AGN 4.6μm luminosities correlate roughly linearly over 4 orders of magnitude, despite of large scatter. We also compare the partition functions of the total integrated 4.6μm and [Oiii] line luminosities from Seyferts and IR-bright LINERs, as function of a variety of host galaxy properties. The result suggests the optical and the IR selected AGNs represent the same galaxy population. We further study the environment of the AGNs, finding a link between the IR nuclear emission and the galaxy interaction.
