Host Galaxy and Nuclear Properties of IR-selected AGNs with and without Outflow Signatures

Abstract

Active galactic nucleus (AGN) driven outflows can have a significant impact on the evolution of the host galaxy. Inthis work, we compare the properties of galaxies that host AGNs with and without outflows. Our sample consists of103 AGNs identified by mid-IR color–color selection and confirmed with optical spectroscopy at a redshift rangeof 0.3 < z < 0.9. We fit the [O III] λ5007 line using spectra from the zCOSMOS survey to identify and study theoccurrence of outflows. We find that ionized outflows are present in ∼25% of our sample, with the largestincidence at the highest [O III] and X-ray luminosity bins. The fastest outflows are found in the more extended andmassive galaxies. We do not observe a difference in the star formation rate of AGNs with outflows compared toAGNs without outflows. From visual inspection and nonparametric morphological studies, we obtain that outflowsare preferentially observed in galaxies with disk-type and elliptical morphologies.
