McFACTS III: Compact Binary Mergers from Active Galactic Nucleus Disks over an Entire Synthetic Universe

The Astrophysical Journal
The active galactic nucleus (AGN) channel for the formation of binary black hole (BBH) mergers has been previously studied as a potential formation channel for the merging compact binaries observed by the LIGO–Virgo–KAGRA (LVK) scientific collaboration ...

The Effects of Active Galactic Nuclei Feedback on the Lyα Forest Flux Power Spectrum

The Astrophysical Journal
We study the effects of active galactic nuclei (AGN) feedback on the Ly α forest 1D flux power spectrum (P1D). Using the Simba cosmological-hydrodynamic simulations, we examine the impact that adding different AGN feedback modes has on the predicted P1D.

UNCOVER Spectroscopy Confirms the Surprising Ubiquity of Active Galactic Nuclei in Red Sources at z > 5

The Astrophysical Journal
The James Webb Space Telescope is revealing a new population of dust-reddened broad-line active galactic nuclei (AGN) at redshifts z ≳ 5. Here we present deep NIRSpec/Prism spectroscopy from the Cycle 1 Treasury program Ultradeep NIRSpec and NIRCam ...

The connection between jets and host galaxies of radio loud AGN: Blazars vs NLSy1s

, 2018
This doctoral dissertation discuss the main properties of the host galaxies of those active galactic nuclei (AGN) capable of generating strong relativistic jets (and therefore, capable of emitting up to the γ−ray energy ranges) and with their jets ...

Clustering, Bias and the Accretion Mode of X-ray selected AGN

, 2013
We present the spatial clustering properties of 1466 X-ray selected AGN compiled from the Chandra CDF-N, CDF-S, eCDF-S, COSMOS and AEGIS fields in the 0.5−8 keV band. The X-ray sources span the redshift interval 0 < z < 3 and have a median value of ž = 0.

Helical Magnetic Fields in AGN Jets

, 2014
We establish a simple model to describe the helical magnetic fields in AGN jets projected on the sky plane and the line-of-sight. This kind of profile has been detected in the polarimetric VLBI observation of many blazar objects, suggesting the existence
