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

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
