Interpreting radiative efficiency in radio-loud AGN

Abstract

Radiative efficiency in radio-loud AGN is governed by the scaled accretion rate on to the central black hole rather than directly by the type of accreted matter; while it correlates with real physical differences, it does not give us unambiguous information about particular objects.
