Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nieto, Daniel | IOP Publishing | 2008-06-01We present the results from a multiwavelength campaign on the TeV blazar 1ES 1959+650, performed in 2006 May. Data from the optical, UV, soft- and hard-X-ray, and very high energy (VHE) gamma-ray ( E > 100 GeV) bands were obtained with the Suza[...]![]()

Barrio Uña, Juan Abel ; Contreras González, José Luis ; Domínguez Díaz, Alberto ; Fidalgo, David Friedrich Carreto ; López Moya, Marcos ; Nievas Rosillo, Mireia ; otros, ... | EDP Sciencies | 2020-01-30Aims. The aim of this study is to search for evidence of a common emission engine between radio giant pulses (GPs) and very-high-energy (VHE, E& x2004;> & x2004;100 GeV) gamma-rays from the Crab pulsar. Methods. We performed 16 h of simultaneou[...]![]()

The gamma-ray binary LS I +61º303 is a well-established source from centimeter radio up to very high energy (VHE; E > 100 GeV). The broadband emission shows a periodicity of ?26.5 days, coincident with the orbital period. A longer (sup[...]![]()

van den Berg, Jacobus P. ; Bottcher, Markus ; Domínguez Díaz, Alberto ; López Moya, Marcos | American Astronomical Society | 2019-03-20We test different physically motivated models for the spectral shape of the gamma-ray emission in a sample of 128 blazars with known redshifts detected by the Fermi Large Area Telescope (LAT) at energies above 50. GeV. The first nine years of LA[...]![]()

Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nieto, Daniel | IOP Publishing | 2008-07-10All but three (M87, BL Lac, and 3C 279) extragalactic sources detected so far at very high energy gamma-rays belong to the class of high-frequency-peaked BL Lac objects. This suggested to us a systematic scan of candidate sources with the MAGIC [...]![]()

We investigate the extension of the very high-energy spectral tail of the Crab Pulsar at energies above 400?GeV. Methods. We analyzed ~320 h of good-quality Crab data obtained with the MAGIC telescope from February 2007 to April 2014. Resu[...]![]()

It has become evident that one-zone synchrotron self-Compton models are not always adequate for very high-energy (VHE) gamma-ray-emitting blazars. While two-component models perform better, they are difficult to constrain due to the lar[...]![]()

We perform an extensive characterization of the broadband emission of Mrk 421, as well as its temporal evolution, during the non-flaring (low) state. The high brightness and nearby location (z=0.031) of Mrk 421 make it an excellent laborat[...]![]()
