Polarization properties of synchrotron sources from simulations of relativistic magnetohydrodynamic turbulence
Luca Del Zanna, Niccolò Bucciantini, Simone Landi
The emission from the relativistically hot plasmas of high-energy astrophysical synchrotron sources, pulsar wind nebulae (PWNe) in particular, depends on the level of magnetic fluc…
A GPU-Accelerated Modern Fortran Version of the ECHO Code for Relativistic Magnetohydrodynamics
Luca Del Zanna, Simone Landi, Lorenzo Serafini +2
The numerical study of relativistic magnetohydrodynamics (MHD) plays a crucial role in high-energy astrophysics, but unfortunately is computationally demanding, given the complex p…
Fast reconnection in relativistic plasmas: the magnetohydrodynamics tearing instability revisited
L. Del Zanna, E. Papini, S. Landi +2
Fast reconnection operating in magnetically dominated plasmas is often invoked in models for magnetar giant flares, for magnetic dissipation in pulsar winds, or to explain the gamm…
The "ideal" tearing mode: theory and resistive MHD simulations
L. Del Zanna, S. Landi, E. Papini +2
Classical MHD reconnection theories, both the stationary Sweet-Parker model and the tearing instability, are known to provide rates which are too slow to explain the observations.…
