1st Abstract

Kes 69, 3C 396, 3C 400.2 are mixed-morphology (MM) Galactic supernova remnants (SNRs), where Kes 69 and 3C 396 are interacting with molecular clouds (MCs). Previous X-ray studies showed that the emission from these SNRs is thermal. It has been suggested that MM SNRs interacting with MCs are potential candidates for overionized plasma in X-rays and hadronic gamma-ray emission. Recently, Chandra observations revealed signs of overionized plasma in 3C 400.2. In this presentation, we give preliminary results of our analysis of the archival Suzaku and Fermi-LAT data of these SNRs and we interpret the outcome.
