Computational General Relativistic Force-Free Electrodynamics: II. Characterization of Numerical Diffusivity
J. F. Mahlmann, M. A. Aloy, V. Mewes +1
Scientific codes are an indispensable link between theory and experiment; in (astro-)plasma physics, such numerical tools are one window into the universe's most extreme flows of e…
Computational General Relativistic Force-Free Electrodynamics: I. Multi-Coordinate Implementation and Testing
J. F. Mahlmann, M. A. Aloy, V. Mewes +1
General relativistic force-free electrodynamics is one possible plasma-limit employed to analyze energetic outflows in which strong magnetic fields are dominant over all inertial p…
Spontaneous creation of circularly polarized photons in chiral astrophysical systems
Adrian del Rio, Nicolas Sanchis-Gual, Vassilios Mewes +3
This work establishes a relation between chiral anomalies in curved spacetimes and the radiative content of the gravitational field. In particular, we show that a flux of circularl…
Numerical relativity in spherical coordinates: A new dynamical spacetime and general relativistic MHD evolution framework for the Einstein Toolkit
Vassilios Mewes, Yosef Zlochower, Manuela Campanelli +4
We present SphericalNR, a new framework for the publicly available Einstein Toolkit that numerically solves the Einstein field equations coupled to the equations of general relativ…
PatchworkWave: A Multipatch Infrastructure for Multiphysics/Multiscale/Multiframe/Multimethod Simulations at Arbitrary Order
Dennis B. Bowen, Mark Avara, Vassilios Mewes +6
We present an extension of the PatchworkMHD code [1], itself an MHD-capable extension of the Patchwork code [2], for which several algorithms presented here were co-developed. Its…
