Modeling the saturation of the Bell instability using Hybrid simulations (Submitted)
G. Zacharegkas, D. Caprioli, C. C. Haggerty, S. Gupta and B. Schroer Abstract: The nonresonant streaming instability (Bell instability) plays a pivotal role in the acceleration and confinement of cosmic rays (CRs); yet, the exact mechanism responsible for its...
The Importance of Heat Flux in Quasi-Parallel Collisionless Shocks (Submitted)
C.C. Haggerty, D. Caprioli, P.A. Cassak, M.H. Barbhuiya, L. Wilson III, D. Turner Abstract: Collisionless plasma shocks are a common feature of many space and astrophysical systems and are sources of high-energy particles and non thermal emission, channeling as much...
Relativistic Asymmetric Reconnection (2022)
R. Mbarek, C.C. Haggerty, L. Sironi, M.A. Shay, and D. Caprioli Abstract: We derive basic scaling equations for relativistic magnetic reconnection in the general case of asymmetric inflow conditions and obtain predictions for the outflow Lorentz factor and the...

Kinetic Simulations of Cosmic-Ray-Modified Shocks II: Particle Spectra (2020)
D. Caprioli, C. C. Haggerty & P. Blasi Abstract: Diffusive shock acceleration is a prominent mechanism for producing energetic particles in space and in astrophysical systems. Such energetic particles have long been predicted to affect the hydrodynamic structure...
Kinetic Simulations of Cosmic-Ray-Modified Shocks I: Hydrodynamics (2020)
C. C. Haggerty and D. Caprioli Abstract: Collisionless plasma shocks are efficient sources of non-thermal particle acceleration in space and astrophysical systems. We use hybrid (kinetic ions – fluid electrons) simulations to examine the nonlinear feedback of the...
dHybridR: a Hybrid–Particle-in-Cell Code Including Relativistic Ion Dynamics (2019)
C. C. Haggerty and D. Caprioli Abstract: We present the first plasma simulations obtained with the code dHybridR, a hybrid particle-in-cell code with fluid electrons and kinetic relativistic ions. dHybridR is perfectly suited for all the astrophysical and...
