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…

Linear Mode Conversion in Ultramagnetized Pair Plasmas: Single-Parameter Scaling

Dawei Dai, Ashley Bransgrove, Anirudh Prabhu +1

In neutron star (NS) magnetospheres, plasma waves propagate as normal modes with distinct propagation dynamics that strongly influence observable signals. This letter presents a un…

Entity -- Hardware-agnostic Particle-in-Cell Code for Plasma Astrophysics. I: Curvilinear Special Relativistic Module

Hayk Hakobyan, Ludwig M. Böss, Yangyang Cai +8

Entity is a new-generation, fully open-source particle-in-cell (PIC) code developed to overcome key limitations in astrophysical plasma modeling, particularly the extreme separatio…

Superluminal Wave Activation at Relativistic Magnetized Shocks

Jens F. Mahlmann, Logan Eskildsen, Arno Vanthieghem +2

Fast radio bursts (FRBs) are extremely energetic radio transients, some are generated in magnetar magnetospheres and winds. Despite a growing number of observations, their emission…

Electrodynamics and dissipation in the binary magnetosphere of pre-merger neutron stars

Jens F. Mahlmann, Andrei M. Beloborodov

We investigate energy release in the interacting magnetospheres of binary neutron stars (BNSs) with global 3D force-free electrodynamics simulations. The system dynamics depend on…

Spindown of Pulsars Interacting with Companion Winds: Impact of Magnetospheric Compression

Yici Zhong, Anatoly Spitkovsky, Jens F. Mahlmann +1

The presence of a companion wind in neutron star binary systems can form a contact discontinuity well within the pulsar's light cylinder, effectively creating a waveguide that conf…
