Relativistic Magnetospheres
Numerical simulations to study the high-energy emission of compact objects
About me
I am a postdoctoral researcher at the Institute for Planetology and Astrophysics (IPAG) in Grenoble, France. In my research, I mainly try to understand how the high-energy emission coming from pulsars and black holes that we observe is produced. To this aim, I use state-of-the-art time-dependent numerical simulations to model the close environment of these compact objects. My numerical simulations are done using a new numerical framework that I developed which is the "Force-free-PIC" hybrid approach.

Publications
Development of a new numerical method to perform global simulations of pulsar magnetospheres, the new approach is a so-called hybrid approach which consists of combining the force-free fluid approach (mass-less limit of MHD) and the Particle-in-cell kinetic approach. This new development was done to answer at the same time a question regarding the numerical aspect of current PIC simulations and to answer astrophysical questions related to gamma-ray pulsars and particle acceleration.
