Radio and X-ray properties of galactic supernova remnants G7.7-3.7 and G344.7-0.1

We report on new radio and X-ray observations of two galactic SNRs: G7.7-3.7 and G344.7-0.1. The high resolution, high sensitivity radio data show several new structures in both remnants. In the X-ray regime, the XMM-Newton data for G7.7-3.7 reveal the existence of thermal soft X-ray emission coinci...
