| Description | We propose observations of two hybrid merging/cooling flow clusters, A115N/S, and A1664/3541 which have bimodal optical and X-ray distributions. Generally, mergers and cooling flows are anticorrelated; mergers appear to destroy cooling flows. We will study the time scale and physical conditions for cooling flow disruption. Both clusters have cooling flow central radio galaxies, which may also act to reheat cooled gas. Both clusters have diffuse cluster radio relic sources, which are usually associated with merger shocks. However, our recent observation of Abell 133 showed that some radio relics may be old radio bubbles from cooling flow central radio sources. We will study the relationship between radio relics, merger shocks, and cooling flow central radio bubbles. |

| 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. |
