摘要：

The Crab Nebula is the most studied object in the gamma-ray sky. Yet there are many important unanswered questions on the interrelation between the gamma-ray emission from the Pulsar and the Nebula. We present the results of 112 hours of observations conducted with the MAGIC Telescopes by using the stereoscopic Sum-Trigger-II, a novel trigger system essentially halving the lower energy threshold of the telescopes. In order to process the data, a dedicated analysis aiming for the lowest energies is applied. From these observations, we detect pulsed gamma-ray emission down to 27 GeV, which allows us to perform a detailed spectral study. Due to the sound statistical basis, we perform short-time variability studies of the Pulsar and test possible correlations with the nebular flares detected by Fermi-LAT.
