Promotionsvortrag von Jan Lukas Schubert

Pulsars are fast-rotating neutron stars that emit pulsed electromagnetic radiation. In particular, the discovery of pulses with energies above 100 GeV raises new questions about the underlying emission mechanisms. So far, only three pulsars in this energy regime are known. The MAGIC telescopes are sensitive from approximately 50 GeV, but can lower their enery threshold down to 20 GeV with optimized trigger criteria (the Sum-Trigger-II) and thus become suitable instruments for the observation of high-energy pulsars. In this work, the Crab and Dragonfly Pulsars are studied. Due to the large amount of data recorded over more than ten years, the analysis is automated. The basis for this is autoMAGIC, a databasesupported tool that enables reproducible analyses with minimal human interaction. The special requirements of pulsar analyses are implemented in autoMAGIC and a standardized dataset for the subsequent production of physical results is generated. In recent years, great efforts have been made in gamma astronomy to standardize the data across different telescopes and to analyze them using unified software. In this context, the open-source project Gammapy was developed. As part of this work, the Python package magicpulsar was developed, which computes the pulsar timing and large parts of the Gammapy analysis based on the standardized dataset from autoMAGIC. The Crab Pulsar is clearly detected based on ∼480 h observation time with 15.47 .. for peak P1, 24.30 .. for peak P2, and 8.85 .. for the bridge. The energy spectra for these peaks and other physically interesting phase ranges are generated and agree with the Fermi-LAT results. A decreasing P1/P2 ratio between ∼20 GeV and ∼800 GeV is observed. The analysis of 27 h of Dragonfly data delivers no pulsed signal.
