Description
The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a
low-energy threshold, has detected very-high-energy gamma rays from a
giant flare of the distant Quasi-Stellar Radio Source (in short: radio
quasar) 3C 279, at a distance of more than 5 billion light-years (a
redshift of 0.536). No quasar has been observed previously in
very-high-energy gamma radiation, and this is also the most distant
object detected emitting gamma rays above 50 gigaelectron volts. Because
high-energy gamma rays may be stopped by interacting with the diffuse
background light in the universe, the observations by MAGIC imply a low
amount for such light, consistent with that known from galaxy counts.

The members of the Particle Astrophysics Group of the IAC participate actively in three large international collaborations of high-energy astrophysics: AMS-02 (Alpha Magnetic Spectrometer), the Cherenkov radiation telescopes MAGIC I and II and the Cherenkov Telescope Array Observatory ( CTAO). We also participate in the ASTRI mini-array, the gamma
