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 cutoff follows a superexponential behavior, the cutoff energy can be as high as ~60 GeV. The upper limit on the flux of pulsed γ-ray emission above 75 GeV is 4.3 × 10-11 photons cm-2 s-1, and the upper limit on the flux of steady emission above 140 GeV is 1.5 × 10-11 photons cm-2 s-1. We discuss our results in the framework of recent model predictions and other studies.7 p.application/pdfeng(c) American Astronomical Society, 2007Astronomia de raigs gammaObservacions astronòmiquesAcceleradors de partículesPúlsarsGamma ray astronomyAstronomical observationsParticle acceleratorsPulsarsinfo:eu-repo/semantics/article5552822020-02-20info:eu-repo/semantics/openAccess
