Hybrid Simulations of Proton Acceleration at Oblique High- Shocks
Yevhen Kylivnyk, Damiano Caprioli, Luca Orusa
Collisionless shocks in the intracluster and intergalactic medium (ICM/IGM) are expected to energize both electrons and ions. While electron acceleration is revealed by prominent r…
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 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,…
Disclosing the catalog pulsars dominating the Galactic positron flux
Luca Orusa, Silvia Manconi, Fiorenza Donato +1
The cosmic-ray flux of positrons is measured with high precision by the space-borne particle spectrometer AMS-02. The hypothesis that pulsars and their nebulae can significantly co…
Fast particle acceleration in 3D hybrid simulations of quasi-perpendicular shocks
Luca Orusa, Damiano Caprioli
Understanding the conditions conducive to particle acceleration at collisionless, non-relativistic shocks is important for the origin of cosmic rays. We use hybrid (kinetic ions --…
A novel prediction for secondary positrons and electrons in the Galaxy
Mattia Di Mauro, Fiorenza Donato, Michael Korsmeier +2
The Galactic flux of cosmic-ray (CR) positrons in the GeV to TeV energy range is very likely due to different Galactic components. One of these is the inelastic scattering of CR nu…
New determination of the production cross section for rays in the Galaxy
Luca Orusa, Mattia Di Mauro, Fiorenza Donato +1
The flux of rays is measured with unprecedented accuracy by the Large Area Telescope from 100 MeV to almost 1 TeV. In the future, the Cherenkov Telescope Array…

The cosmic-ray fluxes of electrons and positrons () are measured with high precision by the space-borne particle spectrometer AMS-02. To infer a precise interpretation of…
Constraining positron emission from pulsar populations with AMS-02 data
Luca Orusa, Silvia Manconi, Fiorenza Donato +1
The cosmic-ray flux of positrons is measured with high precision by the space-borne particle spectrometer AMS-02. The hypothesis that pulsar wind nebulae (PWNe) can significantly c…
Does the Geminga, Monogem and PSR J0622+3749 -ray halos imply slow diffusion around pulsars?
Sarah Recchia, Mattia Di Mauro, Felix A. Aharonian +4
The HAWC Collaboration has reported the detection of an extended -ray emission around the Geminga and Monogem pulsars of a few degree extension. Very recently, the LHAASO Collab…
