Galactic supernova remnants (SNRs) exhibit a wide variety of morphologies which may be the consequence of the type of progenitor star, the explosion mechanism, the presence of a central compact object or the physical conditions of the surrounding interstellar medium (ISM). Multi-wavelength observations are useful tools in the understanding of the role of these different factors and their relevance in the X-ray / radio emission distribution and spectra of the remnants. In this work we present radio and X-ray observations of the galactic SNRs G7.7-3.7 and G344.7-0.1, based on high quality XMM-Newton, VLA and ATCA archival data.
