Exactly energy-conserving electromagnetic Particle-in-Cell method in curvilinear coordinates
Joost Croonen, Luca Pezzini, Fabio Bacchini +1
In this paper, we introduce and discuss an exactly energy-conserving Particle-in-Cell method for arbitrary curvilinear coordinates. The flexibility provided by curvilinear coordina…
Particle-in-cell Simulations of the Magnetorotational Instability in Stratified Shearing Boxes
Astor Sandoval, Mario Riquelme, Anatoly Spitkovsky +1
The magnetorotational instability (MRI) plays a crucial role in regulating the accretion efficiency in astrophysical accretion disks. In low-luminosity disks around black holes, su…
RelSIM: A Relativistic Semi-implicit Method for Particle-in-Cell Simulations
Fabio Bacchini
We present a novel Relativistic Semi-Implicit Method (RelSIM) for particle-in-cell (PIC) simulations of astrophysical plasmas, implemented in a code framework ready for production…
MPI-AMRVAC 3.0: updates to an open-source simulation framework
Rony Keppens, Beatrice Popescu Braileanu, Yuhao Zhou +5
Computational astrophysics routinely combines grid-adaptive capabilities with modern shock-capturing, high resolution spatio-temporal schemes on multi-dimensional hydro- and magnet…
Black Hole Photon Rings Beyond General Relativity
Seppe Staelens, Daniel R. Mayerson, Fabio Bacchini +2
We investigate whether photon ring observations in black hole imaging are able to distinguish between the Kerr black hole in general relativity and alternative black holes that dev…
