EuroHPC SPACE CoE: Redesigning Scalable Parallel Astrophysical Codes for Exascale
Nitin Shukla, Alessandro Romeo, Caterina Caravita +36
High Performance Computing (HPC) based simulations are crucial in Astrophysics and Cosmology (A&C), helping scientists investigate and understand complex astrophysical phenomena. T…
Towards Exascale Computing for Astrophysical Simulation Leveraging the Leonardo EuroHPC System
Nitin Shukla, Alessandro Romeo, Caterina Caravita +16
Developing and redesigning astrophysical, cosmological, and space plasma numerical codes for existing and next-generation accelerators is critical for enabling large-scale simulati…
Nonthermal electron acceleration in turbulent post-flare coronal loops
Clarissa Mora, Fabio Bacchini, Rony Keppens
The generation of nonthermal electrons during solar flares plays a critical role in energy transport from the corona to the chromosphere, producing regions of observed intense X-ra…
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…
Comparing Simulated and Observed Particle Energy Distributions through Magnetic Reconnection in Earth's Magnetotail
Nadja Reisinger, Fabio Bacchini
Magnetic reconnection is an explosive process that accelerates particles to high energies in Earth's magnetosphere, offering a unique natural laboratory to study this phenomenon. T…
Three-dimensional Dynamics of Strongly Magnetized Ion-Electron Relativistic Reconnection
Fabio Bacchini, Gregory R. Werner, Camille Granier +1
We present 3D simulations of semirelativistic collisionless magnetic reconnection, where upstream ions are subrelativistic while electrons are ultrarelativistic. We employ the real…
Driven Collisionless Reconnection of Force-free Flux Tubes: From Onset to Coalescence
Camille Granier, Daniel Groselj, Luca Comisso +1
We investigate the onset of driven collisionless reconnection and plasmoid formation in a magnetically dominated pair plasma, using 2D Particle-in-Cell simulations. Two force-free…
Leaking Outside the Box: Kinetic Turbulence with Cosmic-Ray Escape
Evgeny A. Gorbunov, Daniel Grošelj, Fabio Bacchini
We study particle acceleration in strongly turbulent pair plasmas using novel 3D Particle-in-Cell simulations, featuring particle injection from an external heat bath and diffusive…
Icarus 3.0: Dynamic Heliosphere Modelling
Tinatin Baratashvili, Beatrice Popescu Braileanu, Fabio Bacchini +2
Space weather predictions are necessary to avoid damage caused by intense geomagnetic storms. Such strong storms are usually caused by a co-rotating interaction region (CIR) passin…
