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…
