| ABSTRACT | |
| Unlike AGN feedback in galaxy clusters, in which heating and cooling are balanced at each radius, feedback in early-type galaxies is often overpowered and able in principle to heat the galaxy quickly. How to sustain long-lived ubiquitous jets in such systems remains a puzzle. If a reservoir of quiescent hot gas were maintained in the vicinity of black hole, however, it may continue to power accretion, leading to continuous energy release from the black hole. RGS analysis of a sample of elliptical galaxies showed indications of such feedback in M84. We propose a 380 ks observation of this system with RGS to probe the dynamics of the gas in the inner few kpc and determine whether it is largerly quiescent (in contrast to the galaxy outskirts) and is indeed in heating-cooling imbalance. | |
