On the generation of astrophysically-relevant intermittent magnetic turbulence in the laboratory
Itamar Cohen, Weipeng Yao, Archie F. A. Bott +18
Intermittent magnetic turbulence, namely the presence of non-ordered and clusterized fields, is a ubiquitous phenomenon in space and astrophysical plasmas. It is currently understo…
Hybrid Simulations of Proton Acceleration at Oblique High- Shocks
Yevhen Kylivnyk, Damiano Caprioli, Luca Orusa
Collisionless shocks in the intracluster and intergalactic medium (ICM/IGM) are expected to energize both electrons and ions. While electron acceleration is revealed by prominent r…
Efficient ion re-acceleration in laboratory-produced interpenetrating collisionless shocks
W. Yao, I. Cohen, P. Suarez Gerona +20
Although the origin of cosmic rays (CRs) remains an open question, collisionless magnetized shock waves are widely regarded as key sites for particle acceleration. Recent theories…
SN 1006: A Cosmic Laboratory for Investigating Shock Acceleration Physics
Emma McGinness, Rebecca Diesing, Damiano Caprioli +1
SN 1006 is a historical Type Ia supernova remnant that exhibits non-thermal emission ranging from radio to multi-TeV -rays. Most of this emission (particularly X-rays and -…
Entity -- Hardware-agnostic Particle-in-Cell Code for Plasma Astrophysics. III: Higher-order shape functions & generalized field stencils
Ludwig M. Böss, Arno Vanthieghem, Hayk Hakobyan +2
Modern particle-in-cell (PIC) codes have become an integral tool in plasma astrophysics. As most plasma phenomena grow from initially small instabilities, it is important to ensure…
The role of three-dimensional effects on ion injection and acceleration in perpendicular shocks
Luca Orusa, Damiano Caprioli, Lorenzo Sironi +1
Understanding the conditions that enable particle acceleration at non-relativistic collisionless shocks is essential to unveil the origin of cosmic rays. We employ 2D and 3D hybrid…
