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 [...]![]()

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 [...]![]()

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[...]![]()

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[...]![]()

Aranda, V. M. ; Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | Springer | 2015-06-20Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E > = 6 x 10(19) eV by analyzing cosmic rays [...]![]()

Arqueros Martínez, Fernando ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | IOP Publising LTD | 2014-10-20Spherical harmonic moments are well-suited for capturing anisotropy at any scale in the flux of cosmic rays. An unambiguous measurement of the full set of spherical harmonic coefficients requires full-sky coverage. This can be achieved by combin[...]
