In this work we present the interpretation of the energy spectrum and mass composition data
as measured by the Pierre Auger Collaboration above 6× 1017 eV. We use an astrophysical …

We use a kinetic-equation approach to describe the propagation of ultra high energy cosmic
ray protons and nuclei and calculate the expected spectra and mass composition at the …

Over a century after their discovery, the measurement of the energy spectrum of ultra-high
energy cosmic rays (UHECRs) remains as one of the main issues within the field, being …

The sharp change in slope of the ultrahigh energy cosmic ray (UHECR) spectrum around 1
0 18.6 eV (the ankle), combined with evidence of a light but extragalactic component near …

We present updates on the measurements of the depth of the shower maximum $ X_\rm
{max} $ and the correlation between $ X_\rm {max} $ and the signal in the water-Cherenkov …

Motivated by the recent high-precision measurements of cosmic rays by several new-
generation experiments, we have carried out a detailed study to understand the observed …

We argue that an astrophysical solution to the ultrahigh energy cosmic ray (UHECR)
problem is viable. The detailed study of UHECR energy spectra is performed. The spectral …

We calculate numerically the spectrum of ultra-high energy cosmic rays on Earth assuming
that their sources are distributed in space like the observed galaxies. We use the CfA2 and …

We have previously argued (eg Szabelski et al 2002 Astropart. Phys. 17 125) that the well-
known'ankle'in the cosmic ray energy spectrum, at log E (eV)∼ 18.7–19.0, marks the …
