Jet collimation in NGC 315 and other nearby AGN
B. Boccardi, M. Perucho, C. Casadio +14
Aims. The collimation of relativistic jets in galaxies is a poorly understood process. Detailed radio studies of the jet collimation region have been performed so far in few indivi…
The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 2
B. Lott, D. Gasparrini, S. Ciprini
An incremental version (4LAC-DR2) of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT is presented. This version is associated with the second release…
X-raying winds in distant quasars: the first high-redshift wind duty cycle
E. Bertola, M. Dadina, M. Cappi +6
Theoretical models of wind-driven feedback from Active Galactic Nuclei (AGN) often identify Ultra-fast outflows (UFOs) as being the main cause for generating galaxy-size outflows,…
NGC 3894: a young radio galaxy seen by Fermi-LAT
G. Principe, G. Migliori, T. J. Johnson +7
Context. According to radiative models, radio galaxies may produce gamma-ray emission from the first stages of their evolution. However, very few such galaxies have been detected b…
Radio morphology-accretion mode link in FRII low-excitation radio galaxies
D. Macconi, E. Torresi, P. Grandi +2
Fanaroff-Riley II low-excitation radio galaxies (FRII-LERGs) are characterized by weak nuclear excitation on pc-scales and by properties typical of powerful FRIIs (defined as high-…
