Type: Oral Session: OG 1.4+2.2
Track: OG.1.4
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 ... More

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 ... More

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 ...

Track: OG.1.4
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 ... More

Track: OG.2.2
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 ... More

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 ... More

Track: OG.1.4
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 ...
