Transition from Diffusion to Drift-Dominated Cosmic Ray Transport and the Origin of the Knee
Luis Enrique Espinosa Castro, Carmelo Evoli, Pasquale Blasi
In a magnetic field with a complex topology, as can be the Galactic magnetic field, cosmic ray transport cannot simply be described by diffusion parallel and perpendicular to magne…

The Role of Acoustic Instability in Cosmic-Ray Self-Confinement
Antonio Capanema, Pasquale Blasi, Emanuele Sobacchi
Over the past decades, there has been growing observational and theoretical evidence that cosmic-ray-induced instabilities play an important role in both acceleration and transport…

Excitation of the non-resonant streaming instability around sources of Ultra-High Energy Cosmic Rays
Alessandro Cermenati, Roberto Aloisio, Pasquale Blasi +1
The interpretation of the ultra-high-energy cosmic ray spectrum (UHECRs) and composition suggests a suppression of the flux below 1 EeV, as observed by the Pierre Auger Obser…
