In order to explore how the FR I / FR II dichotomy is related to the nuclear properties of radio galaxies, we studied a complete sample of 26 nearby FR II radio galaxies using Hubble Space Telescope (HST) images and compared them with a sample of FR I previously analyzed. FR I nuclei lie in the radio-optical luminosity plane along a tight linear correlation, which argues for a common synchrotron origin. FR II show a more complex behavior, which is however clearly related to their optical… Expand

The parsec-scale central components of FR I radio galaxies
A majority of a complete sample of 3CR FR I radio galaxies show unresolved optical nuclear sources on the scales of 0.1 arcsec. About half of the 3CR FR II radio galaxies observed with the HST alsoExpand

Jets in Extragalactic Radio Sources
TLDR
Current data indicate that the large-scale jet structures are not moving with relativistic speeds, as previously proposed, and slow-moving jets, which possess turbulent interiors and are dominated by relatively cool gas, can account for the observed jet properties at optical and radio wavelengths.
