Identifying the TeV Gamma-Ray Source MGRO 1908+06

The H.E.S.S. collaboration recently confirmed the Milagro TeV gammaray sourceMGRO 1908+06 and determined its position with sufficient accuracy to allowfollowup observations with XMMNewton. The unusually hard TeV spectrum and thelow Xray to gammaray flux ratio of the source indicate that, unlike mostunidentified TeV sources, it is probably not a pulsar wind nebula but mayrepresent a new class of objects. We propose to observe MGRO 1908+06 in order toidentify its Xray counterpart, determine its location with arcsecond precision,and determine whether it is extended or a point source. The accurate sourceposition provided by XMMNewton will be essential to identify counterparts atother wavelengths and carry out multiwavelength studies of the source. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
