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

Clusters of galaxies in radio

, 2003
Recent results on the radio emission from galaxy clusters are reviewed, with emphasis both on the radio galaxies and on the diffuse radio emission from the intracluster medium. We show that the formation of the tailed morphology in cluster radio galaxies is due to the effect of the cluster gaseous environment and of its large scale motions in merging ...

Very Long Baseline Array Observations of Parsec-scale Radio Emission in Dual Active Galactic Nuclei

The Astrophysical Journal
It is believed that dual active galactic nuclei (AGN) form during galaxy mergers. Studying dual-AGN emission can provide valuable insights into galaxy merging and evolution.

Radio Active Galactic Nuclei Activity in Low Redshift Galaxies Is Not Directly Related to Star Formation Rates

The Astrophysical Journal
We examine the demographics of radio-emitting active galactic nuclei (AGN) in the local Universe as a function of host galaxy properties, most notably both stellar mass ( M _⋆ ) and star formation rate (SFR).

A Galactic-scale Magnetized Wind around a Normal Star-forming Galaxy

The Astrophysical Journal Letters
Galaxy formation theory identifies superwinds as a key regulator of star formation rates, galaxy growth, and chemical enrichment. Thermal and radiation pressure are known to drive galactic-scale winds in dusty starbursting galaxies (e.g., M82), but ...
