XMM Studies of a Millisecond Pulsar Coincident with a Fermi LAT Source
Abstract
We propose to use XMM-Newton to search for X-ray pulsations in the counterpart to a newly-discovered Fermi LAT Source. This source is a binary millisecond pulsar. The radio observations have also found the orbital solution proving the companion has very low mass, suggesting a black widow system. A Chandra image of the LAT field provides possible X-ray counterparts. The radio position suggests one of these is the best candidate although it is not yet definitive. Specific objectives of the XMM search are (1) detect X-ray pulsations, get pulsed flux and light curve, (2) determine off-pulse flux, again to compare with other wavelengths; (3) spectrum of the source as a function of orbital phase.
