High-energy Particle Transport in Three-dimensional Anisotropic Turbulent Magnetic Fields
Daniela Maci, Rony Keppens, Fabio Bacchini
The understanding and modeling of high-energy particles transport in turbulent magnetic fields is an important open question in space- and astrophysics. The multiscale, nonlinear n…
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…
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…
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…
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…
