Self-confinement of relativistic pair beams in magnetized interstellar plasmas: the case of pulsar X-ray filaments
Luca Orusa, Lorenzo Sironi
The observation of filamentary X-ray structures near bow-shock pulsar wind nebulae (PWNe) -- such as the Guitar, Lighthouse, and PSR J20304415 nebulae -- and of slow-diffusion r…
Deep Learning Analysis of Ions Accelerated at Shocks
Paxson Swierc, Damiano Caprioli, Luca Orusa +1
We study the application of deep learning techniques to the analysis and classification of ions accelerated at collisionless shocks in hybrid (kinetic ions--fluid electrons) simula…
Acceleration of Heavy Ions at Non-Relativistic Collisionless Shocks
Damiano Caprioli, Luca Orusa, Miha Cernetic +2
We investigate the process of Diffusive Shock Acceleration (DSA) of particles with mass number to charge number ratios , e.g., partially-ionized heavy ions. To this end, w…
New determination of the neutrino hadronic production cross sections from GeV to beyond PeV energies
Luca Orusa, Mattia Di Mauro, Fiorenza Donato
The flux of astrophysical neutrinos is now measured with unprecedented accuracy and over several decades of energy spectrum. Their origin traces back to hadronic collisions between…
The role of three-dimensional effects on ion injection and acceleration in perpendicular shocks
Luca Orusa, Damiano Caprioli, Lorenzo Sironi +1
Understanding the conditions that enable particle acceleration at non-relativistic collisionless shocks is essential to unveil the origin of cosmic rays. We employ 2D and 3D hybrid…
Precision cross-sections for advancing cosmic-ray physics. Input to the 2026 ESPPU from the XSCRC community
S. Mariani, L. Audouin, E. Berti +32
The latest generation of cosmic-ray direct detection experiments is providing a wealth of high-precision data, stimulating a very rich and active debate in the community on the rel…
Precision cross-sections for advancing cosmic-ray physics and other applications: a comprehensive programme for the next decade
D. Maurin, L. Audouin, E. Berti +32
Cosmic-ray physics in the GeV-to-TeV energy range has entered a precision era thanks to recent data from space-based experiments. However, the poor knowledge of nuclear reactions,…
Criteria for ion acceleration in laboratory magnetized quasi-perpendicular collisionless shocks: when are 2D simulations enough?
Luca Orusa, Vicente Valenzuela-Villaseca
The study of collisionless shocks and their role in cosmic ray acceleration has gained importance through observations and simulations, driving interest in reproducing these condit…
