A multivariate study of mass composition for simulated showers at the Auger South Observatory
Gustavo A. Medina Tanco, Sergio J. Sciutto
The output parameters from the ground array of the Auger South observatory, were simulated for the typical instrumental and environmental conditions at its Malargüe site using the…
UHECR Anisotropy and the Galactic Halo
Gustavo Medina Tanco, Alan A. Watson
Several explanations for the existence of Ultra High Energy Cosmic Rays (UHECR) invoke the idea that they originate from the decay of massive particles created in the reheating fol…
UHECR spectrum: the spatial distribution of the sources
Gustavo Medina Tanco
The Ultra-high energy cosmic ray energy spectrum summarized by the AGASA collaboration indicates clearly that the cosmic ray spectrum extends well beyond the Greisen-Zatsepin-Kuzmi…
Origin and Propagation of Ultra-High Energy Cosmic Rays
Gustavo A. Medina Tanco, Elisabete M. de Gouveia Dal Pino, Jorge E. Horvatth
The existence of cosmic ray particles up to the ultra-high energy limit (> 10^20 eV) is now beyond any doubt. The detection of cosmic particles with such energies imposes a challen…
Large scale structure in the intergalactic magnetic field and ultra-high energy cosmic ray propagation
Gustavo Medina Tanco
The possibility that the magnetic field is strongly correlated with the large-scale structure of the universe has been recently proposed in the literature. In this scenario the int…
Large scale distribution of matter in the nearby universe and ultra-high energy cosmic rays
Gustavo A. Medina Tanco
The deflection of extragalactic ultra-high energy protons (E > 4E19 eV) travelling to our galaxy is studied assuming that visible matter traces both, the sources of the particles a…
