Autonomous RPCs for a Cosmic Ray ground array
Pedro Assis, Alberto Blanco, Nuno Carolino +15
We report on the behaviour of Resistive Plate Chambers (RPC) developed for muon detection in ultra-high energy cosmic ray (UHECR) experiments. The RPCs were developed for the MARTA…
Interferometric Radio Measurements of Air Showers with LOPES: Final Results (ICRC 2017)
Frank G. Schröder, Katrin Link
LOPES was the radio extension of the KASCADE-Grande particle-detector array consisting of up to 30 antennas measuring the radio emission of cosmic-ray air showers between 40 and 80…
The influence of the observatory latitude on the study of ultra high energy cosmic rays
Rita C. dos Anjos, Vitor de Souza, Rogerio M. de Almeida +1
Recent precision measurements of the Ultra High Energy Cosmic Rays (UHECR) arrival directions, spectrum and parameters related to the mass of the primary particle have been done by…
Measurements of the depth of maximum of air-shower profiles at the Pierre Auger Observatory and their composition implications
Vitor de Souza
Air-showers measured by the Pierre Auger Observatory were analyzed in order to extract the depth of maximum (Xmax).The results allow the analysis of the Xmax distributions as a fun…
A new air-shower observable to constrain hadronic interaction models
Raul R. Prado, Vitor de Souza
The energy spectrum of muons at ground level in air showers are studied and a new observable is proposed to constrain hadronic interaction models used in air shower simulations. An…
Limits on the Lorentz Invariance Violation from UHECR astrophysics
Rodrigo Guedes Lang, Humberto Martínez-Huerta, Vitor de Souza
In this paper, Lorentz Invariance Violation (LIV) is introduced in the calculations of photon propagation in the Universe. LIV is considered in the photon sector and the mean free…
