Context. Non-thermal X-ray emission from the shell of Cassiopeia A (Cas A) has been an interesting subject of study, as it provides information about relativistic electrons and their acceleration mechanisms in shocks. The Chandra X-ray observatory revealed the detailed spectral and spatial structure of this supernova remnant in X-rays. The spectral analysis of the Chandra X-ray data of Cas A shows unequal flux levels for different regions of the shell, which can be attributed to different magnetic fields in those regions. Additionally, the GeV gamma-ray emission observed by the Large Area Telescope on board the Fermi Gamma-Ray Space Telescope showed that the hadronic processes are dominating in Cas A, which is a clear signature of acceleration of protons.
