Accretion rates onto massive black holes in four quiescent elliptical galaxies.

WROBEL J.M. and HERRNSTEIN J.R.

Abstract (from CDS):

Four quiescent elliptical galaxies were imaged with the NRAO VLA at 8.5 GHz. Within the context of canonical advection-dominated accretion flows (ADAFs), these VLA images plus published black hole masses constrain the accretion rates to be less than 1.6x10–4, less than 3.6x10–4, ≤7.8x10–4, and ≤7.4x10–4 of the Eddington rates. These ADAF accretion rates derived at 8.5 GHz have important implications for the levels of soft and hard X-rays expected from these quiescent galaxies.
