dc.description.abstractEnWe report the detection of γ -ray pulsations from the high-magnetic-field rotation-powered pulsar PSR J1119−6127 using data from the Fermi Large Area Telescope. The γ -ray light curve of PSR J1119−6127 shows a single, wide peak offset from the radio peak by 0.43±0.02 in phase. Spectral analysis suggests a power law of index 1.0±0.3+0.4 −0.2 with an energy cutoff at 0.8 ± 0.2+2.0 −0.5 GeV. The first uncertainty is statistical and the second is systematic. We discuss the emission models of PSR J1119−6127 and demonstrate that despite the object's high surface magnetic field--near that of magnetars--the field strength and structure in the γ -ray emitting zone are apparently similar to those of typical young pulsars. Additionally, we present upper limits on the γ -ray pulsed emission for the magnetically active PSR J1846−0258 in the supernova remnant Kesteven 75 and two other energetic high-B pulsars, PSRs J1718−3718 and J1734−3333.We explore possible explanations for the non-detection of these three objects, including peculiarities in their emission geometry.
