Abstract:	摘要： We report the discovery of an X-ray periodicity of ~265.3 ms from a deep XMM-Newton observation of the radio-quiet gamma -ray pulsar, PSR J2021+4026, located at the edge of the supernova remnant G78.2+2.1 ( gamma -Cygni). The detected frequency is consistent with the gamma -ray pulsation determined by the observation of the Fermi Gamma-ray Space Telescope at the same epoch. The X-ray pulse profile resembles the modulation of a hot spot on the surface of the neutron star. The phase-averaged spectral analysis also suggests that the majority of the observed X-rays have thermal origins. This is the third member in the class of radio-quiet pulsars with significant pulsations detected from both X-ray and gamma -ray regimes. 出版者： United States 出版日期： 2013-06-10 出處： Astrophysical journal.
