PIC Simulation Methods for Cosmic Radiation and Plasma Instabilities
Martin Pohl, Masahiro Hoshino, Jacek Niemiec
Particle acceleration in collisionless plasma systems is a central question in astroplasma and astroparticle physics. The structure of the acceleration regions, electron-ion energy…
A note on the experiment parameters for the non-resonant streaming instability: competition between left and right circularly polarized modes
Chun-Sung Jao, Sergei Vafin, Ye Chen +10
A non-resonant streaming instability driven by cosmic-ray currents, also called Bell's instability, is proposed as a candidate for providing the required magnetic turbulence of eff…
VERITAS contributions to the 36th International Cosmic Ray Conference
A. U. Abeysekara, A. Archer, W. Benbow +65
Compilation of papers presented by the VERITAS Collaboration at the 36th International Cosmic Ray Conference (ICRC), held July 24 through August 1, 2019 in Madison, Wisconsin.
Multi-messenger interpretation of the neutrinos from TXS 0506+056
Walter Winter, Shan Gao, Xavier Rodrigues +3
We discuss possible interpretations of the neutrinos observed from the AGN blazar TXS 0506+056 in the multi-messenger and multi-wavelength context, including both the 2014-15 and 2…
Kinetic simulations of nonrelativistic perpendicular shocks of young supernova remnants. II. Influence of shock-surfing acceleration on downstream electron spectra
Artem Bohdan, Jacek Niemiec, Martin Pohl +3
We explore electron pre-acceleration at high Mach-number nonrelativistic perpendicular shocks at, e.g., young supernova remnants, which are a prerequisite of further acceleration t…
Precursor Wave Amplification by Ion-Electron Coupling through Wakefield in Relativistic Shocks
Masanori Iwamoto, Takanobu Amano, Masahiro Hoshino +5
We investigated electromagnetic precursor wave emission in relativistic shocks by using two-dimensional particle-in-cell simulations. We found that the wave amplitude is significan…
