Recent Highlights of MAGIC — •Razmik Mirzoyan for the MAGIC collaboration — Max-Planck-Institut für Physik (Werner-Heisenberg-Institut) — Föhringer Ring 6, 80805 München

MAGIC, consisting of two 17m diameter imaging atmospheric Cherenkov telescopes, is a pioneering instrument for doing astrophysics by means of very high energy gamma-rays in the energy range 30 GeV - 100 TeV. The telescopes are located at 2200m a.s.l. in the "Roque de los Muchachos" European Northern Observatory on the Canary island of La Palma. Since 2004 the MAGIC-I stand-alone telescope is taking scientific data. The sensitivity of the detector has been significantly improved by adding the MAGIC-II telescope and operating them in a coincidence (stereo) mode. For boosting the system sensitivity, we upgraded them in 2012. In recent 3-4 years we further boosted the sensitivity of MAGICs at the lowest energies, down to 20-30 GeV, by using the novel SUM-Trigger-2 system and at the very high energies of ~100 TeV, by using the very large zenith angle observation technique. In this report we are going to present the recent highlights of MAGIC, as for example, the gamma-ray observations of Geminga and Crab pulsars at energies above 20 GeV, of Crab Nebula in the range 30 GeV to 100 TeV, measurements of selected AGN, as well as observation of the recent gigantic signal from GRB 190114C, which made a major impact on understanding of the GRB physics.
