The SKA-VLBI Perspective on Radio-Quiet AGN
Francesca Panessa, Tao An, James Petley +21
The accretion-ejection mechanism in Active Galactic Nuclei (AGN) remains a central open problem in astrophysics, tied to the role of AGN feedback in galaxy formation and evolution.…
Clues of the restarting active galactic nucleus activity of Mrk 1498 from GTC/MEGARA integral field spectroscopy data
S. Cazzoli, L. Hernández-García, I. Márquez +4
Some giant radio galaxies selected at X-rays with an AGN show signs of a restarted nuclear activity. One object in this peculiar class is Mrk1498, a giant low-frequency double radi…
The curious activity in the nucleus of NGC 4151: jet interaction causing variability?
D. R. A. Williams, R. D. Baldi, I. M. McHardy +14
A key characteristic of many active galactic nuclei (AGN) is their variability, but its origin is poorly understood, especially in the radio domain. Williams et al. (2017) reported…
Hard X-ray selected giant radio galaxies -- II. Morphological evidence of restarted radio activity
G. Bruni, F. Panessa, L. Bassani +10
About 6% of Radio Galaxies (RG) can reach linear sizes larger than 0.7 Mpc, and are then classified as Giant Radio Galaxies (GRG). The conditions that make possible the formation o…
A young and obscured AGN embedded in the giant radio galaxy Mrk 1498
L. Hernández-García, F. Panessa, L. Bassani +10
Mrk 1498 is part of a sample of galaxies with extended emission line regions (extended outwards up to a distance of 7 kpc) suggested to be photo-ionized by an AGN that has fa…
A discovery of young radio sources in the cores of giant radio galaxies selected at hard X-rays
G. Bruni, F. Panessa, L. Bassani +9
Giant Radio Galaxies (GRG) are the largest single entities in the Universe, having a projected linear size exceeding 0.7 Mpc, which implies that they are also quite old objects. Th…
