Collisionless shocks, that is shocks mediated by electromagnetic processes, are customary
in space physics and in astrophysics. They are to be found in a great variety of objects and …

We evaluate the current status of supernova remnants as the sources of Galactic cosmic
rays. We summarize observations of supernova remnants, covering the whole …

Supernova remnants are beautiful astronomical objects that are also of high scientific
interest, because they provide insights into supernova explosion mechanisms, and because …

Context. Very recent gamma-ray observations of G120. 1+ 1.4 (Tycho's) supernova remnant
(SNR) by Fermi-LAT and VERITAS have provided new fundamental pieces of information for …

We present observations of the young supernova remnant (SNR) RX J1713. 7− 3946 with
the Fermi Large Area Telescope (LAT). We clearly detect a source positionally coincident …

Using three-dimensional magnetohydrodynamic simulations, we investigate general
properties of a blast wave shock interacting with interstellar clouds. The pre-shock cloudy …

We present evidence for cosmic-ray acceleration at the forward shock in Tycho's supernova
remnant (SNR) from three X-ray observables:(1) the proximity of the contact discontinuity to …

Constraints on the diffusion and acceleration parameters in five young supernova remnants
(SNRs) are derived from the observed thickness of their X-ray rims, as limited by the …

We review the observations of supernova remnants (SNRs) and pulsar-wind nebulae
(PWNe) that give information on the strength and orientation of magnetic fields. Radio …

We show that a purely kinetic approach to the excitation of waves by cosmic rays in the
vicinity of a shock front leads to predict the appearance of a non-Alfvénic fast-growing mode …
