Accretion Rates onto Massive Black Holes in Four Quiescent Elliptical Galaxies

Accretion Rates onto Massive Black Holes in Four Quiescent Elliptical Galaxies

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,
