Parallel Collisionless Shocks in strongly Magnetized Electron-Ion Plasma. I. Temperature anisotropies
Mohamad Shalaby, Antoine Bret, Federico Fraschetti
Collisionless electron-ion shocks are fundamental to astrophysical plasmas, yet their behavior in strong magnetic fields remains poorly understood. Using Particle-in-Cell (PIC) sim…

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 $β^-$…

Oscillations of subcritical fast magnetosonic shock boundaries caused by shock reformation
M E Dieckmann, A Bret, D Folini +1
The evolution of a deformed subcritical fast magnetosonic shock front is compared between two two-dimensional PIC simulations with different orientations of the magnetic field rela…
