A 4 MPC X-RAY FILAMENT FALLING INTO THE CLUSTER A85

We propose to observe with EPIC the recently discovered Xray 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 Xray emission due to several Xray 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. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
