The Open Journal of Astrophysics, 2023 Despite the importance of Active Galactic Nuclei (AGN) in galaxy evolution, the mechanisms that fuel AGN activity remain poorly understood. Theoretical models suggest that major mergers of galaxies contribute strongly to AGN fuelling, particularly at ...

An Extended Lyα Outflow from a Radio Galaxy at z = 3.7?
The Astrophysical Journal Letters, 2023 Spatially resolved observations of active galactic nuclei (AGN) host galaxies undergoing feedback processes are one of the most relevant avenues through which galactic evolution can be studied, given the long-lasting effects AGN feedback has on gas ...

The Young, the Old, and the Dusty: Stellar Populations of AGN Hosts [PDF]
, 2011 Studying the average properties of active galactic nuclei (AGN) host stellar populations is an important step in understanding the role of AGN in galaxy evolution and the processes which trigger and fuel AGN activity. Here we calculate model spectral energy distributions (SEDs) that include emission from the AGN, the host galaxy stellar population, and

A Catalog of 406 AGNs in MaNGA: A Connection between Radio-mode AGN and Star Formation Quenching [PDF]
, 2020 Accurate active galactic nucleus (AGN) identifications and spatially resolved host galaxy properties are a powerful combination for studies of the role of AGNs and AGN feedback in the coevolution of galaxies and their central supermassive black holes.

The Evolution of AGN and Their Host Galaxies
, 2016 Active galaxies have been in the forefront of astronomic research since their first discovery, at least 50 years ago (e.g. Schmidt, 1963; Matthews & Sandage, 1963). The putative supermassive black hole (SMBH) at their center characterizes their properties and regulates the evolution of these objects.

The Astrophysical JournalWe 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.

The Astrophysical Journal, 2023 To understand the formation and growth of supermassive black holes (SMBHs) and their coevolution with host galaxies, it is essential to know the impact of environment on the activity of active galactic nuclei (AGNs).

Host galaxy properties of radio selected AGN [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractWith the goal of investigating the link between black hole (BH) and star formation (SF) activity, we study a deep sample of radio selected star forming galaxies (SFGs) and active galactic nuclei (AGNs). Using a multi-wavelength approach we characterize their host galaxies properties (stellar masses, optical colors, and morphology).

$z\sim2$ 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 ($L_{\text{bol,12}}>10^{43}\rm{erg/s}$).
