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.

Dust-Corrected Colors Reveal Bimodality in AGN Host Galaxy Colors at z~1

, 2010
Using new, highly accurate photometric redshifts from the MUSYC medium-band survey in the Extended Chandra Deep Field South (ECDF-S), we fit synthetic stellar population models to compare AGN host galaxies to inactive galaxies at 0.8 < z < 1.2.

The KMOS AGN Survey at High redshift (KASHz) : the prevalence and drivers of ionized outflows in the host galaxies of X-ray AGN [PDF]

, 2015
We present the first results from the KMOS (K-band Multi-Object Spectrograph) AGN (active galactic nuclei) Survey at High redshift (KASHz), a VLT/KMOS integral-field spectroscopic (IFS) survey of z ≳ 0.6 AGN.

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).

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.

The Relation between AGN and Host-galaxy Properties in the JWST Era. I. Seyferts at Cosmic Noon are Obscured and Disturbed

The Astrophysical Journal
The morphology of a galaxy reflects the mix of physical processes occurring within and around it, offering indirect clues to its formation and evolution.

A Radio View of the Sky: the Cosmic History of Star-Forming and AGN Galaxies [PDF]

, 2009
We explore the cosmic evolution of radio detected star forming (SF) galaxies and active galactic nuclei (AGN), drawn from the VLA-COSMOS survey, out to z = 1.3.

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
