The MAGIC gamma-ray telescopes: Highlights and recent developments — •Moritz Hütten for the MAGIC collaboration — Max-Planck-Institut für Physik, München, Germany

MAGIC is a stereoscopic system of two imaging-atmospheric Cherenkov telescopes located on the Canary island of La Palma. MAGIC is measuring very-high-energy (VHE) gamma rays in the range from ∼ 20 GeV to 100 TeV from to date more than 70 astrophysical sources of Galactic and extragalactic origin, up to distances of redshift ∼ 1. During the last years, the instrumental performance was enhanced by several upgrades. In this report, we present recent highlights of the diverse science programme: Galactic observations of the Geminga and Crab pulsars above 20 GeV and of the Crab Nebula up to 100 TeV; the measurement of the extragalactic background light and multi-wavelength observations of AGN flares; and fundamental physics searches for Lorentz Invariance Violation and combined searches for Dark Matter. A special focus will be drawn on MAGIC’s transient programme with multiple recent results, including the discussion of GRB190114C, the first gamma-ray burst found to emit photons at TeV energies.
