The nature of compact radio sources: the case of FR 0 radio galaxies

RD Baldi - The Astronomy and Astrophysics Review, 2023 - Springer
Radio-loud compact radio sources (CRSs) are characterised by morphological compactness
of the jet structure centred on the active nucleus of the galaxy. Most of the local elliptical …

Radio jets from AGNs in dwarf galaxies in the COSMOS survey: mechanical feedback out to redshift∼ 3.4
