The twin-jet system in the FRII radio galaxy 3C 452: A sub-parsec scale VLBI study

Eftychia Madika, Bia Boccardi, Luca Ricci +5

We present a comprehensive multifrequency VLBI analysis of the FRII, high-excitation radio galaxy 3C 452, aiming to resolve and analyze for the first time its twin-jet structure on…

Peering into the heart of 3CR radio galaxies. A very long baseline interferometry perspective on optical-radio classifications at parsec scales

P. Grandi, G. Giovannini, E. Torresi +1

Historically, luminous edge-brightened Fanaroff-Riley type II (FRII) radio galaxies have been associated with radiatively efficient cold accretion disks. In contrast, faint edge-da…

A JVLA, GMRT, and XMM study of Abell 795: Large-scale sloshing and a candidate radio phoenix

N. Rotella, F. Ubertosi, M. Gitti +6

We present a multiwavelength analysis of the galaxy cluster Abell 795 (z=0.1374), known for its extended (200 kpc) radio emission with a steep spectral index of unclear origin surr…

Jet formation studies in AGN: a search for new targets

B. Boccardi, L. Ricci, E. Madika +6

In recent years, the jet formation region in active galaxies has been imaged through mm-VLBI in few ideal targets, first and foremost M87. An important leap forward for understandi…

Fermi-LAT detection of the low-luminosity radio galaxy NGC 4278 during the LHAASO campaign

E. Bronzini, P. Grandi, E. Torresi +1

We present a study of the high-energy properties of the compact symmetric object NGC 4278, recently associated with a TeV source by the Large High Altitude Air Shower Observatory (…

X-ray study of a sample of FR0 radio galaxies: unveiling the nature of the central engine

Eleonora Torresi, Paola Grandi, Alessandro Capetti +2

FR0s are compact radio sources that represent the bulk of the Radio-Loud (RL) AGN population, but they are still poorly understood. Pilot studies on these sources have been already…

The radio/gamma-ray connection in Active Galactic Nuclei in the era of the Fermi Large Area Telescope

M. Ackermann, M. Ajello, A. Allafort +144

We present a detailed statistical analysis of the correlation between radio and gamma-ray emission of the Active Galactic Nuclei (AGN) detected by Fermi during its first year of op…
