Air Fluorescence Relevant for Cosmic-Ray Detection - Summary of the 5th Fluorescence Workshop, El Escorial 2007
Fernando Arqueros, Joerg R. Hoerandel, Bianca Keilhauer
High-energy cosmic rays with energies exceeding eV are frequently observed by measurements of the fluorescence light induced by air showers. A major contribution to the s…
An improved limit to the diffuse flux of ultra-high energy neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +462
Neutrinos in the cosmic ray flux with energies near 1 EeV and above are detectable with the Surface Detector array of the Pierre Auger Observatory. We report here on searches throu…
Air Fluorescence Relevant for Cosmic-Ray Detection - Review of Pioneering Measurements
Fernando Arqueros, Joerg R. Hoerandel, Bianca Keilhauer
Cosmic rays with energies exceeding eV are frequently registered by measurements of the fluorescence light emitted by extensive air showers. The main uncertainty for the…
Modeling crosstalk and afterpulsing in silicon photomultipliers
Jaime Rosado, VÃctor Manuel Aranda, Francisco Blanco +1
An experimental method to characterize the crosstalk and afterpulsing in silicon photomultipliers has been developed and applied to two detectors fabricated by Hamamatsu. An analyt…
Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +447
We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Au…
Implementation of X-rays production in LegPy
Victor Moya, Jaime Rosado, Fernando Arqueros
The LegPy package has been upgraded by including the production of X-ray fluorescence based on a simple model. Several tests have been done to check the validity of our approximati…
An easy tool for the Monte Carlo simulation of the passage of photons and electrons through matter
VÃctor Moya, Jaime Rosado, Fernando Arqueros
A simple Monte Carlo (MC) algorithm for the simulation of the passage of low-energy gamma rays and electrons through any material medium is presented. The algorithm includes severa…
Calibrating laser test-beams for cosmic-ray observatories
Lawrence Wiencke, Fernando Arqueros, John Compton +3
Pulsed UV lasers can provide useful "testbeams" for observatories that use optical detectors, especially fluorescence detectors, to measure high energy cosmic-rays. The light obser…
Relevance of the fluorescence radiation in VHE gamma-ray observations with the Cherenkov technique
Daniel Morcuende, Jaime Rosado, José Luis Contreras +1
Atmospheric fluorescence is usually neglected in the reconstruction of the signals registered by Cherenkov telescopes, both IACTs and wide-angle detector arrays. In this paper we q…
Measurement of the cosmic ray spectrum above eV using inclined events detected with the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +461
A measurement of the cosmic-ray spectrum for energies exceeding eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\…
Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +448
The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared…
The relevance of fluorescence radiation in Cherenkov telescopes
Fernando Arqueros, Jaime Rosado, Daniel Morcuende +1
Cherenkov telescopes are also sensitive to the atmospheric fluorescence produced by the extensive air showers. However this contribution is neglected by the reconstruction algorith…
