Their nature remains mysterious, motivating searches for counterparts at other wavelengths. FRB 12[...]texto impreso

However, no observational evidence of the presence of particles of PeV energies in SNRs has yet been found. The young historical SNR Ca[...]texto impreso

The nearby Perseus cool-core cluster, identified as the most pro[...]texto impreso

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

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
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 [...]texto impreso
