|Title||A 4 MPC X-RAY FILAMENT FALLING INTO THE CLUSTER A85|
|Author||Dr Florence Durret|
|Description||We propose to observe with EPIC the recently discovered X-ray filament that extends 4 Mpc to the southeast of A85 and the impact region where gas and galaxies from the filament are falling into A85. The proposed observations will answer the questions 1. is there diffuse hot gas in the filament or is the X-ray emission due to several X-ray emitting groups; 2. what are the temperatures and metallicities of the gas in the filament and in the impact region; 3. how does material from the filament merge with the main cluster. Accurate temperature and abundance maps of the cluster and cooling flow region also will be obtained.|

|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.
