TL;DR: In this article, a detailed morphological and spatially resolved spectral analysis of the Galactic shell-type supernova remnant (SNR) RX J1713.7-3946 is presented.
Journal ArticleDOI
Observational constraints on energetic particle diffusion in young supernovae remnants: amplified magnetic field and maximum energy
TL;DR: In this article, a joint study of the electrons diffusion and advection in the downstream medium of the supernova shock was carried out, and it was shown that the magnetic field must be amplified up to values between 250 and 500 µG in the case of Cas A, Kepler, and Tycho, or ∼100 µ Gi n in case of SN 1006 and G347.
