Re-observation of Hydra A SE

Galaxy cluster outskirts are the regions where structure formation occursthrough the accretion of smaller structures along largescale filaments.Recently, it has been claimed both from observations and numerical simulationsthat an important fraction of the infalling material should be in the form ofdense clumps. Unfortunately, the observation of the Hydra A SE field, which iscrucial for the completion of our program for the study of gas clumping acceptedin AO11, was badly affected by soft proton flares. This field is located alonga filament, and already allowed us to unveil the presence of accretingsubstructures. Therefore, we ask for a reobservation of this crucial field withXMM, to allow the completion of our AO11 program. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
