Arqueros Martínez, Fernando ; Aab, A. ; Abreu, P. ; Aglietta, M. ; Ahn, E.J. ; Al Samarai, I. ; Albuquerque, I.F.M. ; Allekotte, I. ; Allison, P. ; Almela, A. ; otros, ... | IOP publishing ltd | 2017-03AMIGA (Auger Muons and Infill for the Ground Array) is an upgrade of the Pierre Auger Observatory designed to extend its energy range of detection and to directly measure the muon content of the cosmic ray primary particle showers. The array wil[...]texto impreso
Aranda, V. M. ; Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado, J. ; Vázquez Peñas, José Ramón | American Physical Society | 2015-02-06We present the first hybrid measurement of the average muon number in air showers at ultrahigh energies, initiated by cosmic rays with zenith angles between 62° and 80°. The measurement is based on 174 hybrid events recorded simultaneously with [...]texto impreso
Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | Amer Physical Soc | 2014-07-25The surface detector array of the Pierre Auger Observatory provides information about the longitudinal development of the muonic component of extensive air showers. Using the timing information from the flash analog-to-digital converter traces o[...]texto impreso
Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | IOP publishing ltd | 2016-01To exploit the full potential of radio measurements of cosmic-ray air showers at MHz frequencies, a detector timing synchronization within 1 ns is needed. Large distributed radio detector arrays such as the Auger Engineering Radio Array (AERA) r[...]texto impreso
Cosmic rays are atomic nuclei arriving from outer space that reach the highest energies observed in nature. Clues to their origin come from studying the distribution of their arrival directions. Using 3 x 10? cosmic rays with energies above 8 x [...]texto impreso
Rosado Vélez, Jaime ; Blanco Ramos, Francisco ; Arqueros Martínez, Fernando | Elsevier Science BV | 2014-03The absolute value of the air-fluorescence yield is a key parameter for the energy reconstruction of extensive air showers registered by fluorescence telescopes. In previous publications, we reported a detailed Monte Carlo simulation of the air-[...]texto impreso
Rosado Vélez, Jaime ; Gallego, P. ; García Pinto, Diego ; Blanco Ramos, Francisco ; Arqueros Martínez, Fernando | EDP Sciences | 2013-02-13The uncertainty in the absolute value of the air-fluorescence yield still puts a severe limit on the accuracy in the primary energy of ultra-high-energy cosmic rays. The precise measurement of this parameter in laboratory is in turn conditioned [...]texto impreso
Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | Amer Physical Soc | 2014-03-14The emission of radio waves from air showers has been attributed to the so-called geomagnetic emission process. At frequencies around 50 MHz this process leads to coherent radiation which can be observed with rather simple setups. The direction [...]texto impreso
Arqueros Martínez, Fernando ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Franco Peláez, Francisco Javier ; López Moya, Marcos ; Mirabal Barrios, Néstor ; Nievas Rosillo, Mireia ; Rosado Vélez, Jaime ; Tejedor Álvarez, Luis Ángel | American Astronomical Society | 2017-05-10We perform simulations for future Cherenkov Telescope Array (CTA) observations of RX J1713.7?3946, a young supernova remnant (SNR) and one of the brightest sources ever discovered in very high energy (VHE) gamma rays. Special attention is paid t[...]texto impreso
Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | IOP Publising LTD | 2014We describe the method devised to reconstruct inclined cosmic-ray air showers with zenith angles greater than 60 degrees detected with the surface array of the Pierre Auger Observatory. The measured signals at the ground level are fitted to muon[...]texto impreso
Morcuende, D. ; Rosado, J. ; Contreras González, José Luis ; Arqueros Martínez, Fernando | Elsevier Science BV | 2019-01Atmospheric 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 quantify the fluorescence contribution to the total light recorded[...]texto impreso
Arganda, E. ; Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | IOP Publishing | 2012-04Observations of cosmic rays arrival directions made with the Pierre Auger Observatory have previously provided evidence of anisotropy at the 99% CL using the correlation of ultra high energy cosmic rays (UHECRs) with objects drawn from the Veron[...]texto impreso
Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | IOP publishing ltd | 2016-01This paper presents the results of different searches for correlations between very high-energy neutrino candidates detected by IceCube and the highest-energy cosmic rays measured by the Pierre Auger Observatory and the Telescope Array. We first[...]texto impreso
Arganda, E. ; Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | Elsevier Science BV | 2011-03We present the results of searches for dipolar-type anisotropies in different energy ranges above 2.5 x 10(17) eV with the surface detector array of the Pierre Auger Observatory, reporting on both the phase and the amplitude measurements of the [...]texto impreso
Martínez, S. ; Arqueros Martínez, Fernando ; Fonseca González, Mª Victoria | Elsevier Science BV | 1995-03-15Electromagnetic energy injected into the universe above a few hundred TeV is expected to pile up as ? radiation in a relatively narrow energy interval below 100 TeV due to its interaction with the 2.7^°K background radiation. We present an upper[...]
