Radiative PIC simulations of relativistic pair plasma: multiple interacting current sheets and turbulent evolution
Fulvia Pucci, Elena Amato, Dario Borgogno +5
Two-dimensional relativistic particle-in-cell (PIC) simulations of radiative magnetic reconnection in pair plasmas with multiple interacting current sheets are carried out to mimic…
Accelerating the Particle-In-Cell code ECsim with OpenACC
Elisabetta Boella, Nitin Shukla, Filippo Spiga +3
The Particle-In-Cell (PIC) method is a computational technique widely used in plasma physics to model plasmas at the kinetic level. In this work, we present our effort to prepare t…
Velocity-Space Signatures of Energy Transfer for Ion-Acoustic Instabilities
Mahmoud Saad Afify, Kristopher G. Klein, Mihailo M. MartinoviÄ +1
Context. Observations by Parker Solar Probe (PSP) of electrostatic waves suggest that electrostatic instabilities, including the ion-ion-acoustic instability (IIAI) frequently obse…
Energetic spectra from semi-implicit particle-in-cell simulations of magnetic reconnection
K. M. Schoeffler, F. Bacchini, K. Kormann +2
Astrophysical observations suggest that magnetic reconnection in relativistic plasmas plays an important role in the acceleration of energetic particles. Modeling this accurately r…
Optimal Landau-type closure parameters for two-fluid simulations of plasma turbulence at kinetic scales
Simon Lautenbach, Jeremiah Lübke, Maria Elena Innocenti +2
Two fluid simulations using local Landau-fluid closures derived from linear theory provide an efficient computational framework for plasma modelling, since they bridge the gap betw…
Clustering Wind data at 1 AU to contextualize magnetic reconnection in the solar wind
Francesco Carella, Giovanni Lapenta, Alessandro Bemporad +4
Context. Magnetic reconnection events are frequently observed in the solar wind. Understanding the patterns and structures within the solar wind is crucial to put observed magnetic…
