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

open access: yesThe 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 ...

Environments of high and low excitation radio galaxies

open access: yesAstronomy & Astrophysics
Aims. Active galactic nuclei (AGNs) play a crucial role in shaping galaxy evolution through their feedback mechanisms. Low-excitation radio galaxies (LERGs) and high-excitation radio galaxies (HERGs) are thought to exhibit distinct feedback modes, and ...

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

open access: yesThe 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.

Clusters of galaxies in radio

open access: yes, 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 ...

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

open access: yesThe 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).
