Description | 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. |

Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
