PIC simulation of a thermal anisotropy-driven Weibel instability in a circular rarefaction wave
M. E. Dieckmann, G. Sarri, G. C. Murphy +6
The expansion of an initially unmagnetized planar rarefaction wave has recently been shown to trigger a thermal anisotropy-driven Weibel instability (TAWI), which can generate magn…
Multidimensional simulations of magnetic field amplification and electron acceleration to near-energy equipartition with ions by a mildly relativistic quasi-parallel plasma collision
Gareth C. Murphy, Mark E. Dieckmann, Luke O'C Drury
The energetic electromagnetic eruptions observed during the prompt phase of gamma-ray bursts are attributed to synchrotron emissions. The internal shocks moving through the ultrare…
First detection of VHE gamma-rays from SN 1006 by H.E.S.S
HESS Collaboration, F. Acero, F. Aharonian +175
Recent theoretical predictions of the lowest very high energy (VHE) luminosity of SN 1006 are only a factor 5 below the previously published H.E.S.S. upper limit, thus motivating f…
Particle-in-cell simulation of a mildly relativistic collision of an electron-ion plasma carrying a quasi-parallel magnetic field: Electron acceleration and magnetic field amplification at supernova shocks
M E Dieckmann, G Murphy, A Meli +1
Plasma processes close to SNR shocks result in the amplification of magnetic fields and in the acceleration of electrons, injecting them into the diffusive acceleration mechanism.…
