Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | Elsevier Science BV | 2011-04-11The advent of the Auger Engineering Radio Array (AERA) necessitates the development of a powerful framework for the analysis of radio measurements of cosmic ray air showers. As AERA performs "radio-hybrid" measurements of air shower radio emissi[...]texto impreso
Arganda, E. ; Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | IOP Publishing | 2011-06The Pierre Auger Collaboration has reported. evidence for anisotropy in the distribution of arrival directions of the cosmic rays with energies E > E-th = 5.5 x 10(19) eV. These show a correlation with the distribution of nearby extragalactic o[...]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 ltd | 2012-10The Pierre Auger Observatory is exploring the potential of the radio detection technique to study extensive air showers induced by ultra-high energy cosmic rays. The Auger Engineering Radio Array (AERA) addresses both technological and scientifi[...]texto impreso
Azimuthal asymmetry in the risetime of the surface detector signals of the Pierre Auger Observatory.
Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | Amer Physical Soc | 2016-04-07The azimuthal asymmetry in the risetime of signals in Auger surface detector stations is a source of information on shower development. The azimuthal asymmetry is due to a combination of the longitudinal evolution of the shower and geometrical e[...]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 publishing ltd | 2013-05We derive lower bounds on the density of sources of ultra-high energy cosmic rays from the lack of significant clustering in the arrival directions of the highest energy events detected at the Pierre Auger Observatory. The density of uniformly d[...]texto impreso
Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Vázquez Peñas, José Ramón ; otros, ... | IOP publishing ltd | 2017-04We present a combined fit of a simple astrophysical model of UHECR sources to both the energy spectrum and mass composition data measured by the Pierre Auger Observatory. The fit has been performed for energies above 5.10(18) eV, i.e. the region[...]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 ltd | 2013A thorough search for large-scale anisotropies in the distribution of arrival directions of cosmic rays detected above 10(18) eV at the Pierre Auger Observatory is reported. For the first time, these large-scale anisotropy searches are performed[...]texto impreso
Aranda, V. M. ; Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado, J. ; Vázquez Peñas, José Ramón | American Physical Society | 2014We report a study of the distributions of the depth of maximum, X-max, of extensive air-shower profiles with energies above 10(17.8) eV as observed with the fluorescence telescopes of the Pierre Auger Observatory. The analysis method for selecti[...]texto impreso
Aranda, V. M. ; Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado, J. ; Vázquez Peñas, José Ramón | Amer Physical Soc | 2014-12-31Using the data taken at the Pierre Auger Observatory between December 2004 and December 2012, we have examined the implications of the distributions of depths of atmospheric shower maximum (X-max), using a hybrid technique, for composition and h[...]texto impreso
Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | Amer Physical Soc | 2016-06-14The 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 to the data of the surface detector stations of the Observatory,[...]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 | Elsevier Science BV | 2013-12We describe a new method of identifying night-time clouds over the Pierre Auger Observatory using infrared data from the Imager instruments on the GOES-12 and GOES-13 satellites. We compare cloud. identifications resulting from our method to tho[...]texto impreso
Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Vázquez Peñas, José Ramón | IOP publishing ltd | 2017-02Atmospheric conditions, such as the pressure (P), temperature (T) or air density (rho proportional to P/T), affect the development of extended air showers initiated by energetic cosmic rays. We study the impact of the atmospheric variations on t[...]texto impreso
Más de 100 años después de su descubrimiento, existen todavía interrogantes abiertos sobre el origen y propagación de la radiación cósmica, especialmente en los llamados rayos cósmicos de ultra-alta energía (UHECRs por sus siglas en inglés). El [...]texto impreso
Aranda, V. M. ; Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado, J. ; Vázquez Peñas, José Ramón | Amer Physical Soc | 2015-05-26Neutrinos in the cosmic ray flux with energies near 1 EeV and above are detectable with the Surface Detector array (SD) of the Pierre Auger Observatory. We report here on searches through Auger data from 1 January 2004 until 20 June 2013. No neu[...]
