Query: The jet-disc connection: evidence for a reinterpretation in radio loud
  and radio quiet active galactic nuclei   To constrain models of the jet-disc connection, we explore Eddington ratios
reported in Foschini (2011) and interpret them in relation to the values in
Sikora et al. across the active galactic nuclei population from radio loud
quasars, their flat spectrum radio quasar subclass, the recently discovered
gamma-ray loud narrow-line type 1 Seyfert galaxies, Fanaroff-Riley type I (FRI)
radio galaxies and radio quiet quasars of the Palomar Green survey. While
appeal to disc truncation in radiatively inefficient flow appears to explain
the observed inverse relation between radio loudness and Eddington ratio in
radio loud and radio quiet quasars, FR I objects, scale invariance and recent
data on powerful jets in narrow-line Seyfert 1 galaxies offer compelling
arguments in favour of a reinterpretaion of the jet-disc connection.
