A Morphological Identification and Study of Radio Galaxies from LoTSS DR2. I. The “Winged” Radio Galaxies

The Astrophysical Journal Supplement Series
We conducted an extensive identification and analysis of various morphological classes and subclasses of radio galaxies using the latest high-resolution data from the second data release of the LOFAR Two-metre Sky Survey.

JWST NIRCam Imaging of NGC 4258. I. Observation Overview

The Astrophysical Journal
We present James Webb Space Telescope (JWST) Near-Infrared Camera imaging of the nearby Seyfert 1.9 galaxy NGC 4258, which hosts strong star formation regions as well as an anomalous jet-like radio structure that extends through a significant portion of ...

Radio properties of the quasi-periodic eruption source RXJ1301.9+2747 at parsec scales

Astronomy & Astrophysics
Quasi-periodic eruptions (QPEs) are repeating soft X-ray flares associated with galactic nuclei. Several recent works have found evidence that the accretion flow in the galactic nuclei of QPEs is of recent origin, and that it is unlike canonical active ...

Recognizing Blazars Using Radio Morphology from the VLA Sky Survey

The Astrophysical Journal
Blazars are radio-loud active galactic nuclei whose jets have a very small angle to our line of sight. Observationally, the radio emissions are mostly compact or compact-core with a one-sided jet.

Here Be SDRAGNs—Spiral Galaxies Hosting Large Double Radio Sources

The Astronomical Journal
We present a sample of large double radio sources hosted by spiral galaxies (spiral double radio active galactic nuclei, SDRAGNs). Candidates were initially selected through the Radio Galaxy Zoo project and subsequently refined using Sloan Digital Sky ...

Radio Dim/Gamma-Ray Bright Active Galactic Nuclei

, 2018
Inside virtually every large galaxy lies a supermassive black hole, known as active galactic nuclei. An especially interesting subclass of active galactic nuclei are those that emit high energy radiation.

The Clustering of galaxies around radio-loud active galactic nuclei

, 2013
We examine the hypothesis that mergers and close encounters between galaxies can fuel active galactic nuclei (AGNs) by increasing the rate at which gas accretes toward the central black hole.

Fuelling active galactic nuclei

, 2007
We suggest that most nearby active galactic nuclei are fed by a series of small-scale, randomly oriented accretion events. Outside a certain radius these events promote rapid star formation, while within it they fuel the supermassive black hole.

VaDAR: Varstrometry for Dual AGN Using Radio Interferometry

The Astrophysical Journal
Binary and dual active galactic nuclei (AGNs) are an important observational tool for studying the formation and dynamical evolution of galaxies and supermassive black holes.
