A robust super-time-stepping scheme for Ohmic and ambipolar diffusion
Giancarlo Mattia, Mario Flock, David Melon Fuksman +3
Context. Non-ideal magnetohydrodynamics (MHD) is a key tool for modeling magnetic flux transport in astrophysical systems such as molecular clouds, protostellar cores, and protopla…
2D or not 2D? Exploring 3D relativistic magnetic reconnection dynamics with highly accurate numerical simulations
Vittoria Berta, Matteo Bugli, Andrea Mignone +3
Fast reconnection in magnetically dominated plasmas is widely invoked in models of dissipation in pulsar winds, gamma-ray flares in the Crab nebula, and to explain the radio nanosh…
PyPLUTO: a data analysis Python package for the PLUTO code
Giancarlo Mattia, Daniele Crocco, David Melon Fuksman +5
In recent years, numerical simulations have become indispensable for addressing complex astrophysical problems. The MagnetoHydroDynamics (MHD) framework represents a key tool for i…
Relativistic reconnection with effective resistivity: I. Dynamics and reconnection rate
M. Bugli, E. F. Lopresti, E. Figueiredo +6
Relativistic magnetic reconnection is one of the most fundamental mechanisms considered responsible for the acceleration of relativistic particles in astrophysical jets and magneto…
Magnetic dissipation in short gamma-ray burst jets. I. Resistive relativistic MHD evolution in a model environment
Giancarlo Mattia, Luca Del Zanna, Andrea Pavan +1
Short gamma-ray bursts originate when relativistic jets emerge from the remnants of binary neutron star mergers. Both the jet and the remnant are believed to be strongly magnetized…
