We present the results of a kinetic calculation of the growth rates of
non resonant modes excited by streaming cosmic rays in
non-relativistic shock waves. We show how different assumptions for
the compensating current lead to the appearance of different modes
with different growth rates. We discuss the conditions under which the
modes are non resonant (a la Bell) and lead to large growth rat

Nearly ten years after the discovery of the supernova remnant RX
J0852.0-4622 ("Vela Jr.") with ROSAT in 1998, many important parameters of
the remnant are still largely uncertain. Distance estimates range between
200 pc and 1-2 kpc, with correspondingly different estimates on the time
and type of the supernova explosion. We present the application of our
kinetic theory of cosmic ray accelera

Electron injection process at high Mach number collisionless quasiperpendicular shock
waves is investigated by means of one-dimensional electromagnetic particle-in-cell
simulations. We find that energetic electrons are generated through the following two
steps: (1) electrons are accelerated nearly perpendicular to the local magnetic field
by shock surfing acceleration at the leading edge of th

A particle acceleration mechanism in relativistic shock waves by an action of
radiation pressure is discussed. So far many particle acceleration mechanisms
such as diffusive shock acceleration and shock drift/surfatron acceleration have
been studied as an important energy conversion mechanism, but our
understanding how non-thermal particles are generated is still poor. In this
presentat

The shell-type supernova remnant RX J1713.7--3946 was observed during
three years with the H.E.S.S. Cherenkov telescope system. The first
observation campaign in 2003 yielded the first-ever resolved TeV
gamma-ray image. Follow-up observations in 2004 and 2005 revealed the
very-high-energy gamma-ray morphology of this object with
unprecedented precision and enabled spatially resolved spectral

We present a new code (named MARCOS) aimed at the realistic simulation of diffusive
shock acceleration in its full time-dependent non-linear developments, and more
specifically at the simulation of multiple (ie successive) shocks acceleration as is
believed to occur in many astrophysical places (most notably in superbubbles).
We present briefly the numerical methods implemented, coupling the h

A nonlinear kinetic theory of cosmic ray (CR) acceleration in
supernova remnants (SNRs) is employed to investigate the properties of SNR
RX J1713.7-3946. Observations of the nonthermal radio and X-ray emission
spectra as well as the H.E.S.S. measurements of the very high energy gamma-ray
emission are used to constrain the astronomical and the particle
acceleration par
