First XMM-Newton observations of the globular cluster M 22.
WEBB N.A., GENDRE B. and BARRET D.
Abstract (from CDS):
We have examined preliminary data of the globular cluster, M 22, from the EPIC MOS detectors on board XMM-Newton. We have detected 27 X-ray sources within the centre of the field of view, 24 of which are new detections. Three sources were found within the core of the cluster. From spectral analysis of the X-ray sources, it is possible that the object at the centre of the core is a quiescent X-ray transient and those lying further out are maybe cataclysmic variables.
