Scientific paper

Although cosmic rays are accelerated at the shock front of supernova remnants (SNRs), condition for the particle accelation to occur is poorly understood. One of the ways to resolve this problem is to investigate thermal X-ray emission associated with the acceleration site, because the thermal emission provides us the information of the condistions. We propose XMM-Newton of the SNR CTB37B which has thermal, non-thermal X-ray and TeV γ-ray emission. Suzaku and Chandra observations could not determine the parameters of the thermal plasma because of the contamination of a point source and of statistical limitation. Only good spatial resolution and large effective area of XMM-Newton enable us to investigate the thermal X-ray emission.
