Realistic modeling of wind and supernovae shocks in star clusters: addressing and other problems in Galactic cosmic rays
Siddhartha Gupta, Biman B. Nath, Prateek Sharma +1
Cosmic ray (CR) sources leave signatures in the isotopic abundances of CRs. Current models of Galactic CRs that consider supernovae (SNe) shocks as the main sites of particle accel…
Modeling the Saturation of the Bell Instability Using Hybrid Simulations
Georgios Zacharegkas, Damiano Caprioli, Colby Haggerty
The nonresonant cosmic ray instability, predicted by Bell (2004), is thought to play an important role in the acceleration and confinement of cosmic rays (CRs) close to supernova r…
A numerical approach to the non-uniqueness problem of cosmic ray two-fluid equations at shocks
Siddhartha Gupta, Prateek Sharma, Andrea Mignone
Cosmic rays (CRs) are frequently modeled as an additional fluid in hydrodynamic (HD) and magnetohydrodynamic (MHD) simulations of astrophysical flows. The standard CR two-fluid mod…
