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: In this paper, the MAGIC observations were analyzed for a possible correlation with energy, as suggested by some models of quantum gravity (QG), which predict a vacuum refractive index similar or equal to 1 + (E/M-QGn)(n), n = 1, 2.71 +/- 2.57) x 10(-6) s/GeV2, respectively.

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, an application of the tree classification method Random Forest (RF), as used in the analysis of data from the ground-based gamma telescope MAGIC, is described, and critical issues of the method and its implementation are discussed.

TL;DR: In this paper, the MAGIC collaboration reported the discovery of γ-ray emission from the binary system LS I +61°303 in the TeV energy region, and the authors presented new observational results on this source in the energy range between 300 GeV and 3 TeV.
