We present a catalog of 2-10 keV ASCA Gas Imaging Spectrometer images of fields containing bright sources of GeV emission. The images cover ∼ 85% of the 95% confidence position contour for 28 of the 30 sources with > 1 GeV fluxes above 4 × 10 −8 ph cm −2 s −1 . We find an excess of hard X-ray sources with F 2−10keV 10 −12 ergs cm −2 s −1 positionally coincident with unidentified sources of GeV emission. We comment on radio-loud and radio-quiet pulsar candidates, as well as several SNR and massive binaries as possible sources of the GeV emission. We also find evidence for a class of variable γ−ray sources associated with extended regions of hard X-ray emission, and propose that for these sources, a significant percentage of the γ−ray emission is generated in synchrotron nebulae surrounding fast, young pulsars.

“…Nebulae luminosity and spectrum depend on properties of the wind and the pressure confining the pulsar. Following the Kennel-Coroniti model (1984a, b) for the Crab, we have developed a scheme in which nebulae are used as calorimeter to detect wind paramters (Shibata, Kawai and Tamura 1997).…”

Recent observation with ASCA reveals that radio pulsars own X-ray diffuse nebulae around them. 11 such nebulae have been reported (Harrus, Hughes & Helfand 1996, Shibata et al. 1997, Kawai, Tamura & Shibata 1997). It is most likely that these nebulae are synchrotron nebuale powered by the pulsar wind, the outflow of relativistic particles. Kawai, Tamura and Shibata (1997) reduced an empirical law for the nebula luminosity Lx as a function of the rotation power Ėrot of the central pulsar: Lx/Ėrot = −12.3 + 0.27 log Ėrot.

“…The existence of X-ray-bright pulsar-wind nebula as a common feature surrounding rotation-powered pulsars was recently reported on the basis of ASCA observations . Indeed, the ASCA data taken from PSR 0656+14, 1055-52, and Geminga (as well as from other pulsars) show a faint, diffuse, and somewhat clumpy emission around these pulsars, interpreted as a result of an interaction of a pulsar wind outflow with the surrounding interstellar matter Shibata et al 1997). The ROSAT (and if available the BeppoSAX) data of these sources were re-analyzed recently by with the aim to search for faint point sources which-due to the wide ASCA point-spread function of about 3 arcmin (FWHM)-could result in such a pattern of diffuse emission and knots in the ASCA data.…”

Recent X-ray observatories such as ROSAT, ASCA, RXTE, BeppoSAX, and Chandra have achieved important progress in neutron star and pulsar astronomy. The identification of Geminga as a rotation-powered pulsar, the discovery of X-ray emission from millisecond pulsars, and the identification of cooling neutron stars are only a few of the fascinating results. In the following, I will give a brief review on the X-ray emission properties of rotation-powered pulsars and their wind nebulae.
