Coherent radio pulses from showers in different media: A unified parameterization
Jaime Alvarez-Muñiz, Enrique Marqués, Ricardo A. Vázquez +1
We study the frequency and angular dependences of Cherenkov radio pulses originated by the excess of electrons in electromagnetic showers in different dense media. We develop a sim…
On the energy determination of extensive air showers through the fluorescence technique
J. Alvarez-Muñiz, E. Marqués, R. A. Vázquez +1
The determination of the shower development in air using fluorescence yield is subject to corrections due to the angular spread of the particles in the shower. This could introduce…
Calculation Methods for Radio Pulses from High Energy Showers
J. Alvarez-Muñiz, R. A. Vázquez, E. Zas
We present an approximation for the numerical calculation of Cherenkov radio pulses in the Fraunhofer limit from very high energy showers in dense media. We compare it to full Mont…
Radiodetection of neutrino interactions in ice
J. Alvarez-Muñiz, R. A. Vázquez, E. Zas
We study the Cherenkov radiopulses emitted in PeV and EeV neutrino interactions in ice. We discuss how the rich radiation pattern in the 100 MHz to 1 GHz frequency range, in princi…
High Energy Cosmic Rays from Neutrinos
J. J. Blanco-Pillado, R. A. Vázquez, E. Zas
We discuss recent models in which neutrinos, which are assumed to have mass in the eV range, originate the highest energy cosmic rays by interaction with the enhanced density in th…
Characterization of neutrino signals with radiopulses in dense media through the LPM effect
J. Alvarez-Muñiz, R. A. Vázquez, E. Zas
We discuss the possibilities of detecting radio pulses from high energy showers in ice, such as those produced by PeV and EeV neutrino interactions. It is shown that the rich radia…
Gamma Ray Bursts as seen by a Giant Air Shower Array
C. O. Escobar, P. L. Da Silva, R. A. Vázquez
The potentiality of a Giant Shower Array to low energy gamma rays from gamma ray bursts is discussed. Effective areas are calculated for different scenarios and the results are enc…
Are High Energy Cosmic Rays Magnetic Monopoles?
C. O. Escobar, R. A. Vázquez
We argue that magnetic monopoles can not be associated to the highest energy cosmic rays as recently suggested. Both the observed spectrum and the arrival direction disagree with o…
Limits on Topological Defect Neutrino fluxes from Horizontal Air Shower measurements
J. J. Blanco-Pillado, R. A. Vázquez, E. Zas
We obtain the horizontal air shower rate from the (EeV) high energy neutrino flux predicted in some topological defect scenarios as the source for the highest energy cosmic rays. E…
