High-energy nonthermal radiation from putative Geminga-like gamma-ray pulsars.

JIN Z., JIANG Z.J. and ZHANG L.

Abstract (from CDS):

The gamma-ray spectra of some unidentified Galactic sources show that the corresponding counterparts are likely gamma-ray pulsars. We investigate the possibility of some Geminga-like gamma-ray pulsars as the counterparts of unidentified sources. There are five Geminga-like gamma-ray pulsar candidates associated with 3EG J0010+7309, 3EG J1835+5918, 3EG J2020+4017, 3EG J0616-3310, and 3EG J1249-8330. Combining the observed nonthermal X-ray emission detected by Chandra or XMM-Newton and the gamma-ray emission by EGRET, we study the high-energy radiation from these putative pulsars based on the revised vacuum outer gap model. By comparing the estimated spectra with the observations, we estimated the spin parameters and the inclination angles for these five putative pulsars. The observed spectra of the unidentified gamma-ray sources can be explained by this outer gap model.
