Sub-sonic compressible magnetohydrodynamic turbulence I. Alfvénic and fast-magnetosonic injection, amplitude dependence, and compressibility effects
Eleonora Puzzoni, Silvio Sergio Cerri, Dimitri Laveder +2
We investigate how sub-sonic compressible magnetohydrodynamic (MHD) turbulence properties that are relevant for cosmic-ray (CR) transport in the Galaxy are affected by the nature a…
Polarized 3D Synthetic Turbulence I: Magnetic Field Line Random Walk
Matthieu Bouchet, Yoann Génolini, Silvio S. Cerri +2
The behavior of magnetic field lines in a turbulent plasma is a key property of the medium, with important consequences for plasma dynamics and charged-particle transport. We study…
Particle acceleration at recollimation shocks in sub-relativistic jets A model for jets in Seyfert Galaxies, Microquasars and Protostellar Systems
Enrico Peretti, Elena Amato, Silvio Sergio Cerri +3
Context: Growing observational evidence suggests that sub-relativistic astrophysical jets may accelerate particles at slowly evolving standing shocks. Recollimation shocks are expe…
Characterization of local energy transfer in large-scale intermittent stratified turbulent flows via coarse graining
Raffaello Foldes, Raffaele Marino, Silvio Sergio Cerri +1
Recent studies based on simulations of the Boussinesq equations indicate that stratified turbulent flows can develop large-scale intermittency in the velocity and temperature field…
