An Excess of Active Galactic Nuclei Triggered by Galaxy Mergers in MaNGA Galaxies of Stellar Mass ∼1011 M ⊙

The Astrophysical Journal
To facilitate new studies of galaxy-merger-driven fueling of active galactic nuclei (AGNs), we present a catalog of 387 AGNs that we have identified in the final population of over 10,000 z < 0.15 galaxies observed by the Sloan Digital Sky Survey-IV ...

Relativistic Jet Motion in the Radio-quiet LINER Galaxy KISSR 872

The Astrophysical Journal
We report superluminal jet motion with an apparent speed of β _app = 1.65 ± 0.57 in the radio-quiet (RQ) low-ionization nuclear emission-line region (LINER) galaxy KISSR 872.

Ensemble Variability Properties of Active Galactic Nuclei in the SDSS DR17

The Astrophysical Journal
We present the results from a study of ∼9600 broadline-selected active galactic nuclei (AGNs) with host galaxies detected from the Sloan Digital Sky Survey (SDSS) Data Release 17.

Large-scale environments of star-forming active galactic nuclei: How black-hole mass, accretion rate, and luminosity connect to dark-matter halos

Astronomy & Astrophysics
Understanding the relative roles of large-scale environment and internal host-galaxy processes in shaping active galactic nuclei (AGN) activity is key to constraining models of black-hole growth and galaxy evolution. In this work, we investigated how the

A Deep Chandra View of A2597: Bubbles, Shocks, Cold Fueling, and a Plasma Depletion Layer

The Astrophysical Journal
To examine how active galactic nucleus (AGN) feedback shapes the intracluster medium (ICM) and fuels black hole accretion in the cool-core galaxy cluster A2597, we present deep (∼600 ks) Chandra X-ray observations complemented by archival GMRT radio and ...
