Study of the new superluminal source XTE J1748-288 in quiescence

XTEJ1748288 is a new member of the still small class (only 3 objects) of thegalactic sources that show apparent superluminal motion. Very little informationis available yet on this source. We therefore ask for an XMM Open Time 30 ksobservation of XTEJ1748288 in its quiescent state. The goal is the study of the spectral characteristics of the source in its (normal) state of very low flux,in which only a large area experiment like EPIC can provide a high significantdetection of the spectral characteristics and features. In particular, the highspatial resolution of EPIC will mostly eliminate the problems due tocontamination by nearby sources, therefore allowing for a detailed study of theprofile of the Fe line expected in this source. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
