Search for X-ray Counterparts in Pulsar-like High-b Unassociated Fermi Sources

The Fermi Large Area Telescope has been very successful at discovering gammaraypulsars. As we extend the search to dimmer sources, the larger positionuncertainty makes discovery more challenging. We propose to observe a set of 6LATdetected high Galactic latitude gammaray sources that have pulsarlikegammaray spectra but no asyet identified counterparts in any other waveband.These sources have been detected by LAT with high significance and are likelynearby gammaray pulsars. The proposed observations are for 20 ks per source,covering the LAT error region in a single pointing. We will determine the Xrayposition, flux, and spectral properties for any sources detected by XMMNewtonwithin this region. This proposal follows successful XMM programs we proposed in Cycles 8 and 9. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
