Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nievas Rosillo, Mireia ; Satalecka, Konstanzja ; otros, ... | EDP Sciencies | 2016-05Clusters of galaxies are expected to be reservoirs of cosmic rays (CRs) that should produce diffuse ?-ray emission due to their hadronic interactions with the intra-cluster medium. The nearby Perseus cool-core cluster, identified as the most pro[...]![]()

PKS 1510-089 is a flat spectrum radio quasar strongly variable in the optical and GeV range. To date, very high-energy (VHE, > 100 GeV) emission has been observed from this source either during long high states of optical and GeV activi[...]![]()

Barrio Uña, Juan Abel ; Contreras González, José Luis ; Domínguez Díaz, Alberto ; Carreto Fidalgo, David Friedrich ; Fonseca González, Victoria ; López Moya, Marcos ; Nievas Rosillo, Mireia ; otros, ... | EDP SCIENCES S A | 2018-09-13Aims. The very high energy (VHE greater than or similar to 100 GeV) gamma-ray MAGIC observations of the blazar S4 0954+65, were triggered by an exceptionally high flux state of emission in the optical. This blazar has a disputed redshift of z = [...]![]()

Antoranz Canales, Pedro ; Barrio Uña, Juan Abel ; Contreras González, José Luis ; Fonseca González, Mª Victoria ; López Moya, Marcos ; Miranda Pantoja, José Miguel ; Nievas Rosillo, Mireia | EDP Sciencies | 2016-11Context. QSO B0218+357 is a gravitationally lensed blazar located at a redshift of 0.944. The gravitational lensing splits the emitted radiation into two components that are spatially indistinguishable by gamma-ray instruments, but separated by [...]![]()
