Identification of INTEGRAL Sources in the Galactic Plane

While significant progress is being made on identifying the nature of thenumerous hard Xray IGR sources that have been discovered by the INTEGRALsatellite, a significant fraction still remain unclassified. Our group has beenfocusing on studies of the IGR sources in the Galactic plane, many of which areHigh Mass Xray Binaries with extreme properties, such as strong variability andvery high levels of local absorption. For both IGR J01363+6610 and IGRJ175072856, short Chandra observations have left several possible but nodefinite counterparts, and we propose XMMNewton observations of these twosources to find the correct soft Xray counterpart. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
