The Astrid Simulation: Evolution of Black Holes and Galaxies to z = 0.5 and Different Evolution Pathways for Galaxy Quenching

The Astrophysical Journal
We present new results from the ASTRID simulation from z = 3 to z = 0.5, covering the epoch of cosmic noon. The galaxy stellar mass function, as well as the black hole mass and luminosity functions in ASTRID , exhibit good agreement with recent ...

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.

Properties of Galaxies Hosting X-ray Selected Active Galactic Nuclei in the Cl1604 Supercluster at z=0.9 [PDF]

, 2008
To investigate the role of feedback from Active Galactic Nuclei (AGN) in driving the evolution of their host galaxies, we have carried out a study of the environments and optical properties of galaxies harboring X-ray luminous AGN in the Cl1604 ...

Black hole variability and the star formation-active galactic nucleus connection : do all star-forming galaxies host an active galactic nucleus? [PDF]

, 2014
We investigate the effect of active galactic nucleus (AGN) variability on the observed connection between star formation and black hole accretion in extragalactic surveys.

Agn & Host Galaxy Scaling Relations

, 2018
IBISCO is a new multi-dimensional study of AGN scaling relations in a complete unbiased sample of local AGN, carried-on with IRAM, ALMA and INTEGRAL. For the first time we have included the information on the molecular gas reservoirs into the scaling relations between AGN and host galaxy properties.

Investigating the Star Formation Rates of Active Galactic Nucleus Hosts Relative to the Star-forming Main Sequence

The Astrophysical Journal
A fundamental question in galaxy and black hole evolution remains how galaxies and their supermassive black holes have evolved together over cosmic time.
