TL;DR: The Cherenkov Telescope Array (CTA) as discussed by the authors is a very high-energy (VHE) gamma ray observatory with an international collaboration with more than 1000 members from 27 countries in Europe, Asia, Africa and North and South America.

TL;DR: 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 3C 279, at a distance of more than 5 billion light-years.

TL;DR: The Cherenkov Telescope Array (CTA) as mentioned in this paper is the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond, covering a huge range in photon energy from 20 GeV to 300 TeV.

TL;DR: By developing a new electronic trigger, the threshold of the MAGIC telescope is lowered, revealing a relatively high cutoff energy in the phase-averaged spectrum, which indicates that the emission occurs far out in the magnetosphere, hence excluding the polar-cap scenario as a possible explanation of the measurement.

TL;DR: In this paper, the authors report on the observation of gamma-rays above 25 ε,GeV from the Crab pulsar (PSR B0532+21) using the MAGIC I telescope.
