Constraints on the steady and pulsed very high energy Gamma-Ray emission from observations of PSR B1951+32/CTB 80 with the MAGIC Telescope

We report on very high energy γ-ray observations with the MAGIC Telescope of the pulsar PSR B1951+32 and its associated nebula, CTB 80. Our data constrain the cutoff energy of the pulsar to be less than 32 GeV, assuming the pulsed γ-ray emission to be exponentially cut off. In the case that the cuto...
