Compact radio galaxies: the case of FR0s
R. D. Baldi, A. Capetti, G. Giovannini +20
Fanaroff-Riley type 0 (FR0) radio galaxies, a newly-identified and abundant population of low-power radio-loud active galactic nuclei, present a significant challenge to our unders…
Powerful Radio Sources in the Southern Sky. IV. Observations of the G4Jy-3CRE Catalog with the Australian Square Kilometre Array Pathfinder
Siegfried A. Gawenda, Juan P. Madrid, Francesco Massaro +19
A recent 2023 paper by Massaro et al. introduced the G4Jy-3CRE, a new catalog of the brightest radio sources in the southern hemisphere that serve as a southern equivalent to the T…
The MUSE view of Lyman- nebulae in High redshift Radio Galaxies
Miguel Coloma Puga, Barbara Balmaverde, Alessandro Capetti +2
We present the results of VLT/MUSE integral field spectroscopic observations of the Ly emission nebulae associated with 11 high redshift () radio galaxies (HzRGs)…
Jet properties of FR0 radio galaxies: need for VLBI data
R. D. Baldi, G. Giovannini, A. Capetti +1
Fanaroff-Riley (FR) type 0 radio galaxies are a subclass of radio-loud active galactic nuclei (AGN) that lack extended kpc-scale jets, different from the classical FRI and FRII rad…
A 20 kiloparsec bipolar Lyman outflow from a radio galaxy at z=2.95
Miguel Coloma Puga, Barbara Balmaverde, Alessandro Capetti +3
The study of ionized gas kinematics in high-z active galaxies plays a key part in our understanding of galactic evolution, in an age where nuclear activity was widespread and star…
Powerful Radio-Loud Quasars are Triggered by Galaxy Mergers in the Cosmic Bright Ages
Peter Breiding, Marco Chiaberge, Erini Lambrides +14
While supermassive black holes are ubiquitous features of galactic nuclei, only a small minority are observed during episodes of luminous accretion. The physical mechanism(s) drivi…
