Ultra-high energy cosmic rays (UHECRs) interacting with the atmosphere generate extensive air showers (EAS) of secondary particles. The depth corresponding to the maximum development of the shower, $\Xmax$, is a well-known observable for determining the nature of the primary cosmic ray which initiated the cascade process. In this paper, we present an empirical model to describe the distribution of $\Xmax$ for EAS initiated by nuclei, in the energy range from $10^{17}$ eV up to $10^{21}$ eV, and…

HERMES: a Monte Carlo Code for the Propagation of Ultra-High Energy Nuclei
Although the recent experimental efforts to improve the observation of Ultra-High Energy Cosmic Rays (UHECRs) above $10^{18}$ eV, the origin and the composition of such particles is still unknown. In
Energetics of ultrahigh-energy cosmic-ray nuclei
Energetics of the ultrahigh-energy cosmic rays (UHECRs) generated in the universe is crucial for pinning down their candidate sources. Using the recent Auger data on UHECR spectra, we calculate the
Energy generation rate densities of ultrahigh-energy cosmic-ray nuclei
The origin of ultrahigh-energy cosmic-ray (UHECR) has been a mystery for many years. In order to identify candidate sources, it is crucial to figure out the energetics of cosmic-ray sources. By
HERMES: Simulating the propagation of ultra-high energy cosmic rays
Abstract.The study of ultra-high energy cosmic rays (UHECR) at Earth cannot prescind from the study of their propagation in the Universe. In this paper, we present HERMES, the ad hoc Monte Carlo code
Ultrahigh-energy cosmic-ray nuclei and neutrinos from engine-driven supernovae
Transrelativistic supernovae (SNe), which are likely driven by central engines via jets or winds, have been among candidate sources of ultrahigh-energy cosmic rays (UHECRs). We investigate

We present a new method to infer the mass composition of ultra-high energy cosmic rays performing simultaneous modifications of the simulated depth of shower maximu ($X_{\rm max}$) and the ground

Recently, the energy determination of extensive air showers using radio emission has been shown to be both precise and accurate. In particular, radio detection offers the opportunity for an

Measurement of the depth of maximum of extensive air showers above 10{18} eV.
TLDR
The measurement of the depth of maximum, X{max}, of the longitudinal development of air showers induced by cosmic rays is described and the interpretation of these results in terms of the cosmic ray mass composition is briefly discussed.
Indications of proton-dominated cosmic-ray composition above 1.6 EeV.
TLDR
These measurements constrain models in which the galactic-to-extragalactic transition is the cause of the energy spectrum ankle at 4x10(18) eV, and are consistent with a predominantly protonic composition of cosmic rays when interpreted via the Q GSJET01 and QGSJET-II high-energy hadronic interaction models.
"Ridge" in proton-proton scattering at 7 TeV.
TLDR
It is shown that a hydrodynamical expansion based on flux tube initial conditions leads in a natural way to the observed structure in the two-particle correlation function.
The Pierre Auger Collaboration
The Pierre Auger Collaboration has reported evidence for anisotropies in the arrival directions of cosmic rays with energies larger thanEth = 55 EeV. There is a correlation above the isotropic
