1D PIC Simulations of Resonant Scattering-Driven Pair Cascades in Magnetar Magnetospheres
Jens F. Mahlmann, Alexander A. Philippov, Adrien Soudais +2
Hard X-rays in persistent magnetar emission originate from radiative processes in pair-loaded magnetospheric plasma, yet self-consistent kinetic simulations of such radiation-rich…

Emergence of cyclic flux eruptions in kinetic simulations of magnetized spherical accretion onto a Schwarzschild black hole
Enzo Figueiredo, John Mehlhaff, Adrien Soudais +1
The dynamics of black hole magnetospheres critically depend on the black hole spin and on the structure of the accretion flow. In the limit of a Schwarzschild black hole immersed i…

Scaling up global kinetic models of pulsar magnetospheres using a hybrid force-free-PIC numerical approach
Adrien Soudais, Benoît Cerutti, Ioannis Contopoulos
The particle-in-cell approach has proven effective at modeling neutron star and black hole magnetospheres from first principles, but global simulations are plagued with an unrealis…
