Radio emission in star-forming galaxies: connection to restarted or relic AGN activity
Astronomy & AstrophysicsIncreasing evidence shows that active galactic nuclei (AGNs) with radio detections have more perturbed ionized gas kinematics and higher outflow detection rates, suggesting a link between radio emission and these processes.

Relativistic jets in narrow-line Seyfert 1 galaxies. New discoveries and open questions
EPJ Web of Conferences, 2013 Before the launch of the Fermi satellite only two classes of AGNs were known to produce relativistic jets and thus emit up to the γ-ray energy range: blazars and radio galaxies, both hosted in giant elliptical galaxies.

The Clustering Of Galaxies Around Radio-Loud AGNs
, 2013 We examine the hypothesis that mergers and close encounters between galaxies can fuel AGNs by increasing the rate at which gas accretes towards the central black hole.

Radio Galaxies at TeV Energies: Preface
Galaxies, 2020 The majority of the known extragalactic sky from TeV gamma-ray energies consists of blazars having plasma jets pointing in the direction of the line-of-sight, which results in a large Doppler boosting of their emission.

Radio Galaxies—The TeV Challenge [PDF]
Galaxies, 2018 Over the past decade, our knowledge of the γ -ray sky has been revolutionized by ground- and space-based observatories by detecting photons up to several hundreds of tera-electron volt (TeV) energies. A major population of the γ -ray bright objects are active galactic nuclei (AGN) with their relativistic jets pointed along our line-of-sight ...

Dynamics of Powerful Radio Galaxies
Galaxies, 2023 Analytical models describing the dynamics of lobed radio sources are essential for interpretation of the tens of millions of radio sources that will be observed by the Square Kilometre Array and pathfinder instruments. We propose that historical models can be grouped into two classes in which the forward expansion of the radio source is driven by ...
