Searching for soft gamma-ray pulsars in unassociated Fermi LAT sources with XMM

Fermi has detected over 200 gammaray pulsars of varying types in 8 years ofoperations, but the socalled soft (< 100 MeV) gammaray pulsars remainrelatively elusive. Typically singlepeaked, younger and more energetic than GeVpulsars, such pulsars were particularly hard to detect with Fermi prior to therelease of Pass 8. Increasing the size of this population may shed light on ourcurrent understanding of highenergy pulsars and the effect that variousparameters (e.g. geometry) may have on the observed emission. We propose short5ks XMM observations of our top 5 soft gammaray pulsar candidates to enable thefirst sensitive blind searches for such pulsars using LAT data below 100 MeV. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
