MAGIC Obsevations of Pulsars with the Sum-Trigger-II — •Ceribella Giovanni for the MAGIC collaboration — Max-Planck-Institut für Physisk, München, Deutschland

MAGIC is a stereoscopic system of two Imaging Atmospheric Cherenkov Telescopes at 2200 m above see level, on the Spanish Canary Island of La Palma. During the first 15 years of activity, MAGIC gave birth to the observation of VHE pulsars from the ground with the discovery of the emission above 25 GeV of the Crab Pulsar, and continued contributing to the study of this object through multiple observation campaigns.

In the last years a low-energy trigger system, the Sum-Trigger-II, has been put into operation. This made MAGIC a very proficient instrument for the observation of soft gamma-ray emitters such as pulsars. This recently led to the detection of pulsed gamma rays from the Geminga pulsar, which became the third known object of its kind to be observed with IACTs.

In this talk we will review MAGIC results in the field of VHE pulsars with Crab and Geminga data. In addition, we will present technical details on the Sum-Trigger-II.
