Does the Jet Production Efficiency of Radio Galaxies Control Their Optical AGN Types?

S Trippe - arxiv preprint arxiv:1408.5948, 2014 - arxiv.org
The jet production efficiency of radio galaxies can be quantified by comparison of their
kinetic jet powers P_jet and Bondi accretion powers P_B. These two parameters are known …

The peaked spectrum and compact steep spectrum sources: Issues and opportunities

C O'Dea - Astronomische Nachrichten, 2021 - Wiley Online Library
The peaked spectrum (PS) radio sources are sub‐kpc in size and have a peak in the radio
spectrum. The compact steep specrum (CSS) sources range from about 1 kpc to an adopted …

The multi-phase ISM of radio galaxies: a spectroscopic study of ionized and warm gas
