13. Detection of ultra high energy Tau neutrinos in fuorescence detectors / Detecção de neutrinos do Tau de altissimas energias em detetores de fluorescencia
Fazemos uma estimativa do número de Chuveiros Atmosféricos Extensos originados por neutrinos do tau em Detetores de Fluorescência como os do Observatório Pierre Auger. Consideramos modelos de produção de neutrinos do elétron e do múon de altíssimas energias em objetos extra galácticos e Defeitos Topológicos, assim como mudança de sabor na propaga

14. Desenvolvimento e produção das lentes dos telescopios do Observatorio Auger / Development and production of Auger Observatory telescope lenses
Since before its discovery, the study of cosmic rays and its effect has deeply stimulated theorists and experimentalists. Today, one of the great challenge is a explanation of the existence of the ultra high energy cosmic rays, that overcome energies of 1020 eV ~ 16 J. With the goal to investigate the most energetic part of the spectrum, in particular energi

15. Pierre Auger Observatory: status report
The Pierre Auger Observatory is a large international effort to provide measurements of extensive air showers (EAS) initiated in the upper atmosphere by cosmic rays with energies above 10(18) eV , the Ultra High Energy Cosmic Rays (UHECR's). The explanations for the origin, acceleration processes and composition of the UHECR's face theoretical and experiment

16. Implications of a possible clustering of highest-energy cosmic rays
Recently, a possible clustering of a subset of observed ultra-high energy cosmic rays above ≃40 EeV (4 × 1019 eV) in pairs near the supergalactic plane was reported. We show that a confirmation of this effect would provide information on the origin and nature of these events and, in case of charged primaries, imply interesting constraints on the extragala
