Abstract We propose to observe with EPIC the recently discovered X-ray filamentthat extends 4 Mpc to the southeast of A85 and the impact region wheregas and galaxies from the filament are falling into A85. The proposedobservations will answer the questions 1. is there diffuse hot gas inthe filament or is the X-ray emission due to several X-ray emittinggroups; 2. what are the temperatures and metallicities of the gas inthe filament and in the impact region; 3. how does material from thefilament merge with the main cluster. Accurate temperature andabundance maps of the cluster and cooling flow region also will beobtained.

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.
