Sursauts radio rapides par chocs magnétisés relativistes dans les magnétosphères des magnétars // Fast Radio Burst Generation by Relativistic Magnetized Shocks in Magnetar Magnetospheres

The project aims to improve our understanding of the most successful leading physical dissipative process at the origin of FRBs: 'relativistically magnetized shock waves'. In such extreme environments, where magnetic fields routinely reach 10^15 G within a dilute electron-positron plasma, the shock wave is mediated by collective plasma effects, such as fast magnetosonic solitons, which may emit in the radio band and be interpreted as FRBs. Using the open-source CPU-GPU coordinate-agnostic particle-in-cell (PIC) code ENTITY, the aim of the doctoral thesis is to characterize the dynamics of these shock waves, their long-term evolution, and their observational signature.
