Relativistic Magnetohydrodynamic Simulations of Giant Magnetar Bursts
Koushik Chatterjee, Alexander Philippov, Andrei M. Beloborodov +3
Gradual crustal deformation can generate strongly twisted magnetic fields around magnetars, potentially triggering giant flares with total energies exceeding $10^{44}\,\mathrm{erg}…
Effect of magnetic field inclination on black hole jet power and particle acceleration
Enzo Figueiredo, Benoît Cerutti, Kyle Parfrey
Rotating black holes are known to launch relativistic jets and accelerate particles provided they accrete a magnetized plasma. However, it remains unclear how the global magnetic f…
Particle Acceleration in Collisionless Magnetically Arrested Disks
Jesse Vos, Benoit Cerutti, Monika Moscibrodzka +1
We present the first collisionless realization of two-dimensional axisymmetric black hole accretion consistent with a persistent magnetically arrested disk state. The accretion flo…
Improved Dimensionality Reduction for Inverse Problems in Nuclear Fusion and High-Energy Astrophysics
Jonathan Gorard, Ammar Hakim, Hong Qin +2
Many inverse problems in nuclear fusion and high-energy astrophysics research, such as the optimization of tokamak reactor geometries or the inference of black hole parameters from…
