Search for X-ray Counterparts in Pulsar-like High-Lat Unidentified Fermi Sources

The Fermi Large Area Telescope has been very successful at discovering gammaraypulsars in blind searches. As we extend the search to dimmer pulsars, theincreasing source location uncertainty makes discovery more challenging. Wepropose to observe a selected set of 8 LATdetected high Galactic latitudegammaray sources that have pulsarlike gammaray spectra but no asyetidentified counterparts in any other waveband. These sources have been detectedby the LAT with high significance and are likely nearby gammaray pulsars. Theproposed observations are for 10 ks per source, covering the Fermi LAT sourceerror region in a single pointing. We will determine the Xray position, flux,and spectral properties in the 0.210 keV energy band for any sources detected by XMMNewton within this region. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
