The Merging Galaxy Cluster Environment Affects the Morphology of Radio Active Galactic Nuclei

The Astrophysical Journal
It has previously been found that the galaxy cluster environment can affect the fueling and evolution of active galactic nuclei (AGN). This work examines the effect of the merging cluster environment on the properties of radio AGN by comparing the radio ...

Delayed and Fast-rising Radio Flares from an Optical and X-Ray-detected Tidal Disruption Event in the Center of a Dwarf Galaxy

The Astrophysical Journal Letters
AT 2018cqh is a unique tidal disruption event (TDE) discovered in a dwarf galaxy. Both the light-curve fitting and galaxy scaling relationships suggest a central black hole mass in the range of 5.9 < log M _BH / M _☉ < 6.4. The r-band peak luminosity is ∼

Cosmological zoom-in simulation of odd radio circles as merger-driven shocks in galaxy groups

Astronomy & Astrophysics
Context. A new class of distinct radio objects, commonly referred to as odd radio circles (ORCs), has been recently discovered. The origin of these features remains unclear because their peculiar properties challenge our current understanding of ...

Radio loud far-infrared galaxies [PDF]

The first results are presented of a multiwavelength study of Infrared Astronomy Satellite (IRAS) galaxies with excess radio emission. The sample was selected by cross correlating the IRAS Faint Source Survey, and the Point Source Catalogue with the ...

ASKAP J005512.2−255834: A Luminous, Long-lived Radio Transient at z = 0.1—an Orphan Afterglow or an Off-nuclear TDE from an IMBH?

The Astrophysical Journal
We report the discovery of a slowly evolving, extragalactic radio transient, ASKAP J005512.2–255834 (hereafter ASKAP J0055–2558), identified using the Australian SKA Pathfinder in a search for orphan afterglows associated with archival gravitational-wave
