Abstract

We have recently discovered a tight correlation between the Bondi accretion rate and kinetic jet power in nearby, X-ray bright elliptical galaxies with active central sources and clear radio bubbles. This correlation implies an instantaneous efficiency of ~2 per cent for the conversion of energy associated with the rest mass of accreted matter into jet power. Here we seek to address the time-averaged efficiency with which energy is fed back into the surrounding gas in elliptical galaxies. We propose Chandra X-ray observations of a complete optical magnitude, X-ray flux, X-ray luminosity and distance-limited sample of nearby elliptical galaxies. Our results will have important implications for models of gas accretion, jet formation and galaxy formation.
