A Population View of the Cosmic-Ray Knee: The Role of Variance in Supernova Maximum Rigidities
Carmelo Evoli
The broad shape of the Galactic cosmic-ray knee challenges source models in which all supernova remnants share a nearly universal, sharp maximum rigidity. We investigate whether th…
Observation of the Moon and Sun shadows with cosmic rays at an average energy of eV
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +346
Interactions of cosmic rays with the Moon and the Sun produce deficits in their arrival-direction distributions relative to an isotropic flux. Such shadows have been observed previ…
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…
Bounds on Lorentz invariance violation from muon fluctuations at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +357
Quantum gravity theories often modify spacetime symmetries. In particular, Lorentz invariance may be violated when approaching the Planck scale. Although the scales at which intera…
Depth of Maximum of Air-Shower Profiles above 10^17.7 eV Measured with the Fluorescence Detector of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +358
We present measurements of the depth of shower maximum, Xmax, for cosmic-ray-induced extensive air showers recorded by the fluorescence detector of the Pierre Auger Observatory ove…
Exploring memory-burdened primordial black holes with ultra-high-energy cosmic-rays
Antonio Ambrosone, Marco Chianese, Carmelo Evoli
Quantum backreaction effects may quench Hawking evaporation through a ``memory burden'', allowing primordial black holes (PBHs) with formation masses well below $10^{15}~\mathrm{g}…
