No evidence for a different accretion mode for all 3CR FR I radio galaxies

Abstract:

We have analyzed the optical and radio properties of a sample of 3CR FR I radio galaxies which have Hubble Space Telescope imaging capable of detecting optical cores. The jet powers of the FR I radio galaxies are estimated from their low-frequency radio luminosities, and the optical core luminosity is taken as an upper limit on the emission from any unobscured accretion disc. We argue that if the accretion discs in these sources are assumed to be advection dominated accretion flows (ADAFs), o...
