Factors Controlling the Statistics of Magnetic Reconnection in MHD Turbulence
M. B. Khan, M. A. Shay, S. Oughton +9
We study the statistics of dynamical quantities associated with magnetic reconnection events embedded in a sea of strong background magnetohydrodynamic (MHD) turbulence using direc…
The Importance of Heat Flux in Quasi-Parallel Collisionless Shocks
Colby C. Haggerty, Damiano Caprioli, Paul A. Cassak +3
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 as 20…
Acceleration of Heavy Ions at Non-Relativistic Collisionless Shocks
Damiano Caprioli, Luca Orusa, Miha Cernetic +2
We investigate the process of Diffusive Shock Acceleration (DSA) of particles with mass number to charge number ratios , e.g., partially-ionized heavy ions. To this end, w…
Efficient Particle Acceleration in 2.5-Dimensional, Hybrid-Kinetic Simulations of Decaying, Supersonic, Plasma Turbulence
Keyan Gootkin, Colby Haggerty, Damiano Caprioli +1
Collisionless, turbulent plasmas surround the Earth, from the magnetosphere to the intergalactic medium, and the fluctuations within them affect nearly every field in the space sci…
A "Faux-Shock" Method for Hybrid Simulations of Astrophysical Shocks
Emily R. Simon, Damiano Caprioli, Colby C. Haggerty +1
We demonstrate a novel setup for hybrid particle-in-cell simulations designed to isolate the physics of the shock precursor over long time periods for significantly lower computati…
Plasma Instabilities Dominate Radioactive Transients Magnetic Fields: The self-confinement of leptons in Type Ia and Core-Collapse Supernovae, and Kilonovae
Dhvanil D. Desai, Colby C. Haggerty, Benjamin J. Shappee +8
The light curves of radioactive transients, such as supernovae and kilonovae, are powered by the decay of radioisotopes, which release high-energy leptons through $β^+$ and $β^-$…
