Nonlinear Decay of Fast Magnetosonic Waves through Weak Turbulence: Force-Free Electrodynamics Simulations
Siddhant Solanki, Jens Mahlmann, Alexander Philippov
We investigate the propagation of low-frequency fast-magnetosonic (FMS) waves in highly magnetized environments. Such conditions are relevant to the escape of GHz fast radio bursts…
Damping of Fast Radio Bursts in the Inner Magnetospheres of Magnetars
Siddhant Solanki, Jens Mahlmann, Alexander Philippov +1
We investigate the propagation of fast radio bursts (FRBs) through magnetar magnetospheres. Previous work showed that, in the inner magnetosphere, GHz radio waves propagate as fast…
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…
Modeling of lightcurves from reconnection-powered very high energy flares from M87*
Siddhant Solanki, Jordy Davelaar, Bart Ripperda +1
The black hole at the center of M87 is observed to flare regularly in the very high energy (VHE) band, with photon energies GeV. The rapid variability, which can be a…
