$z\sim2$ dual AGN host galaxies are disky: stellar kinematics in the ASTRID Simulation
The Open Journal of AstrophysicsWe 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 ($L_{\text{bol,12}}>10^{43}\rm{erg/s}$).

Black hole mass, host galaxy mass, and dark matter halos: Testing the environmental connection
Astronomy & AstrophysicsWe investigate the relation between supermassive black holes (SMBHs), their host galaxies, and large-scale dark-matter halos by combining broad-line X-ray active galactic nuclei (AGNs) from the XMM–XXL and Stripe 82X surveys with galaxies from VIPERS and

The Astrophysical JournalWe 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-

The Astrophysical Journal Letters, 2023 We study the properties of galaxies hosting mid-infrared outbursts in the context of a catalog of 500,000 galaxies from the Sloan Digital Sky Survey. We find that nuclear obscuration, as inferred by the surrounding dust mass, does not correlate with host

The location and kinematics of the emission line regions in Active Galactic Nuclei [PDF]
, 2008 This thesis contains the results from a study of the optical emission lines of various samples of active galactic nuclei (AGN). We have used three separate techniques to determine the precise kinematics and the relative location of the emission line ...

The Astrophysical JournalIn Paper I, we exploited the unsurpassed resolution and depth of JWST/NIRCam imagery to investigate the relationship between active galactic nuclei (AGN) and host-galaxy properties in the JWST era, finding a correlation between the level of spatial ...
