Aromatic Features in AGNs: Star‐forming Infrared Luminosity Function of AGN Host Galaxies [PDF]

The Astrophysical Journal, 2007
We describe observations of aromatic features at 7.7 and 11.3 um in AGN of three types including PG, 2MASS and 3CR objects. The feature has been demonstrated to originate predominantly from star formation. Based on the aromatic-derived star forming luminosity, we find that the far-IR emission of AGN can be dominated by either star formation or nuclear ...

Active Galactic Nucleus Pairs from the Sloan Digital Sky Survey. II. Evidence for Tidally Enhanced Star Formation and Black Hole Accretion

, 2011
Active galactic nuclei (AGNs) are occasionally seen in pairs, suggesting that tidal encounters are responsible for the accretion of material by both central supermassive black holes (BHs). In Paper I of this series, we selected a sample of AGN pairs with

Statistics of the projected angles between the black-hole spin and the host-galaxy rotation axes from NewHorizon

Astronomy & Astrophysics
Understanding the alignment between active galactic nucleus (AGN) jets and their host galaxies is crucial for interpreting AGN unification models, jet feedback processes, and the coevolution of galaxies and their central black holes (BHs). In this study,

SSDSS IV MaNGA - Properties of AGN host galaxies

, 2017
We present here the characterization of the main properties of a sample of 98 AGN host galaxies, both type-II and type-I, in comparison with those of about 2700 non-active galaxies observed by the MaNGA survey. We found that AGN hosts are morphologically early-type or early-spirals.

Active Dwarf Galaxy Database. I. Overlap between Active Galactic Nuclei Selected by Different Techniques

The Astrophysical Journal
We assemble a sample of 733 dwarf galaxies ( M _* ≤ 10 ^9.5 M _⊙ ) with signatures of active galactic nuclei (AGN) and explore the intersection between different AGN-selection techniques.
