The non-thermal universe at the highest energies: TeV gamma-ray astronomy with the MAGIC telescope

Some os the most violent processed in the universe present a non-thermal spectrum reaching energies of several tens of TeV. Due to the low fluxes at these energies, we need a technique capable to achieve collection areas of the order of the km^2. This can be reached by the Imaging Atmospheric Cherenkov technique and MAGIC is one of the main detectors for performing ground-based observations using this technique. It consists of two 17m diameter Imaging Atmospheric Cherenkov telescopes that are located at 2200 m a.s.l. at the Roque de los Muchachos, on the Canary island of la Palma, Spain. They are designed to observe gamma rays with energies above ~50 GeV. The system is currently taking data with an unprecedented integral sensitivity of 0.66% Crab Units above 220 GeV. In this presentation I will report about the status of the telescopes and the most recent physics highlights, including the extreme variability of the radio galaxy IC310, studies of the Crab Nebula, the very-high-energy bridge emission of the Crab pulsar and the highest-energy pulsed signal ever detected, the discovery of the pulsar wind nebula 3C 58 at TeV energies, dark matter studies and observations of new sources. Finally, we will have a glimpse to the future of the TeV gamma-ray astronomy with the next-generation world-wide facility CTA.
