****************************************************** PR # 41222 We propose to observe the cluster of galaxies A3627 which contains a radio galaxy as its cD galaxy. The target of this observation is to measure the non-thermal pressure support in the cluster. Here we propose to measure the non-thermal pressure with the radio lobes associated the cD radio galaxy. Pressure comes from magnetic field and high energy electron will be estimated by measuring inverse Compton X-ray, while thermal pressure of the hot gas filling the cluster will also be estimated by observing soft X-ray spectrum from the cluster. Thus the rest non-thermal pressure in the cluster will be determined with this ASCA observation. ******************************************************
