Barrio Uña, Juan Abel ; Contreras González, José Luis ; Domínguez Díaz, Alberto ; Carretero Fidalgo, David Friedrich ; Fonseca González, Victoria ; Hoang, Kim Dinh ; López Moya, Marcos ; Nievas Rosillo, Mireia ; Peñil del Campo, Pablo ; Saha, Lab ; otros, ... | EDP SCIENCES S A | 2018-11-20Context. 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[...]texto impreso
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 = [...]texto impreso

The BL Lac object S5 0716+714, a highly variable blazar, underwent an impressive outburst in January 2015 (Phase A), followed by minor activity in February (Phase B). The MAGIC observations were triggered by the optical flux observed in[...]texto impreso
