The impact of nuclear equations of state on the dynamics and multi-messenger emission of magnetorotational stellar explosions
Andrea Celati, Matteo Bugli, Luca Del Zanna +2
The gravitational collapse of massive stars at the end of their life leads to powerful supernova explosions that produce compact objects, regulate the dynamics of host galaxies, an…
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…
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…
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…
A Fourth-Order Finite Volume Scheme for Resistive Relativistic Magnetohydrodynamics
Andrea Mignone, Vittoria Berta, Marco Rossazza +4
We present a finite-volume, genuinely 4th-order accurate numerical method for solving the equations of resistive relativistic magnetohydrodynamics (Res-RMHD) in Cartesian coordinat…
