Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
The Pierre Auger Collaboration
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest energies, which are correlated with the…
Galactic neutrino background from cosmic ray interaction with the ISM content
C. De Donato, G. A. Medina-Tanco, J. C. D'Olivo
We use a diffusive model for the propagation of Galactic cosmic rays to estimate the charged pion production in interactions with protons of the interstellar medium. Cosmic ray nuc…
Astrophysics Motivation behind the Pierre Auger Southern Observatory Enhancements
Gustavo Medina-Tanco
The Pierre Auger Collaboration intends to extend the energy range of its southern observatory in Argentina for high quality data from 0.1 to 3 EeV. The extensions, described in acc…
Lateral distribution and the energy determination of showers along the ankle
G. Ros, G. A. Medina-Tanco, C. De Donato +6
The normalization constant of the lateral distribution function (LDF) of an extensive air shower is a monotonous (almost linear) increasing function of the energy of the primary. T…
Trapping of strangelets in the geomagnetic field
L. Paulucci, J. E. Horvath, G. A. Medina-Tanco
Strangelets coming from the interstellar medium (ISM) are an interesting target to experiments searching for evidence of this hypothetic state of hadronic matter. We entertain the…
The Galactic Center as a point source of neutrons at EeV energies
G. Medina-Tanco, A. G. O. Krone-Martins
The central region of our Galaxy is a very peculiar environment, containing magnetic fields in excess of 100 mG and gas densities reaching ~ 10^4cm^-3. This region was observed as…
