Consequently, gamma-rays of differ[...]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
