Barrio Uña, Juan Abel ; Contreras González, José Luis ; Domínguez Díaz, Alberto ; Carreto Fidalgo, David Friedrich ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nievas Rosillo, Mireia ; otros, ... | EDP Sciencies | 2018-12-14Aims. We aim to characterize the multiwavelength emission from Markarian 501 (Mrk 501), quantify the energy-dependent variability, study the potential multiband correlations, and describe the temporal evolution of the broadband emission within l[...]texto impreso

The MAGIC telescopes detected a fast, very-high-energy (VHE, E > 100 GeV) gamma-ray flare from BL Lacertae on 2015 June 15. T[...]texto impreso
Barrio Uña, Juan Abel ; Bonnefoy, Simon Francois Albert ; Contreras González, José Luis ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Nievas Rosillo, Mireia | EDP Sciencies | 2017-07Context. The extragalactic very-high-energy gamma-ray sky is rich in blazars. These are jetted active galactic nuclei that are viewed at a small angle to the line-of-sight. Only a handful of objects viewed at a larger angle are so far known to e[...]texto impreso

During the campaign, the n[...]texto impreso
Nievas Rosillo, Mireia | 2012-07-02Las imágenes de todo el cielo han demostrado ser una potente herramienta para determinar la calidad astronómica del cielo, y su uso se está extendiendo hoy en día tanto ubicaciones de futuros observatorios como en los ya existentes. El observato[...]texto impreso

The absence of simultaneous data at lower energies led to an incomplete characterization of the broadband spectral energy distribu[...]texto impreso

The observations were triggered by high ac[...]texto impreso
The search for detection of ?-rays from distant AGNs by Imaging Atmospheric Cherenkov Telescopes (IACTs) is challenging at high redshifts, not only because of lower flux due to the distance of the source, but also due to the consequent absorptio[...]texto impreso
Zamorano Calvo, Jaime ; Sánchez de Miguel, Alejandro ; Nievas Rosillo, Mireia ; Tapia Ayuga, Carlos ; Ocaña González, Francisco ; Izquierdo Gómez, Jaime ; Gallego Maestro, Jesús ; Pascual Ramírez, Sergio | 2015-07-15The SQM network of the Spanish Light Pollution Research collaboration (http://guaix.fis.ucm.es/splpr/SQM-REECL) is growing with the help of amateur astronomers and interested citizens. Up to now there are 18 stations. SQM photometers provide mea[...]texto impreso

We study the multi-band variability and correlations of the TeV blazar Mrk 421 on year time scales, which can bring additional insight on the processes responsible for its broadband emission. Methods. We observed Mrk 421 in the very high e[...]texto impreso
