Star Formation Characteristics of Galaxies Hosting AGN
We present an analysis of the ultra-violet (UV) observations of two Seyfert type active galactic nuclei (AGN), namely NGC 4051 and NGC 4151. These observations aimed at studying the star formation in the hosts of these AGN were carried out with the ultra-violet imaging telescope on board AstroSat in far-UV.

Image decomposition of barred galaxies and AGN hosts [PDF]
I present the results of multi-component decomposition of V and R broadband images of a sample of 17 nearby galaxies, most of them hosting bars and active galactic nuclei. I use BUDDA v2.1 to produce the fits, allowing to include bars and AGN in the models. A comparison with previous results from the literature shows a fairly good agreement.

$z\sim2$ dual AGN host galaxies are disky: stellar kinematics in the ASTRID Simulation
We study dual AGN host galaxy morphologies at $z=2$ using the ASTRID simulation, selecting black hole (BH) pairs with small separation ($\Delta r10^7M_\odot$), and luminosity ($L_{\text{bol,12}}>10^{43}\rm{erg/s}$).

Host galaxy evolution in radio-loud AGN [PDF]
Abstract We investigate the luminosity evolution of the host galaxies of radio-loud AGN through Hubble Space Telescope imaging of 72 BL Lac objects. This sample has enabled us to avoid the biases implicit in quasar studies. We find that the host galaxies of BL Lacs evolve strongly, consistent with that observed in the hosts of other radio-loud AGN ...

We investigate the stellar shape and size–mass relationship of X-ray-selected active galactic nucleus (AGN) host galaxies using the high angular resolution and deep sensitivity in the near-infrared of the COSMOS-Web JWST survey field. We present the rest-

Decomposition of AGN host galaxy images
We describe an algorithm to decompose deep images of Active Galactic Nuclei into host galaxy and nuclear components. Currently supported are three galaxy models: A de-Vaucouleurs spheroidal, an exponential disc, and a two-component disc+bulge model. Key features of the method are: (semi-)analytic representation of a possibly spatially variable point ...

We investigate the connection between accretion signatures and host galaxy properties in the context of how active dwarf galaxies are identified. We use the database constructed in E. J. Wasleske & V. F.

Pair-Matching of Radio-Loud and Radio-Quiet AGNs
Active galactic nuclei (AGNs) are known to cover an extremely broad range of radio luminosities and the spread of their radio-loudness is very large at any value of the Eddington ratio.
