The Arches cluster is an extraordinarily compact massive star cluster with a core radius of about 10'' (~0.4 pc) and consisting of more than 150 O star candidates with initial stellar masses greater than 20 M near G0.12-0.02. X-ray observations of the radio Arc near the Galactic center at l ~ 02, which contains the Arches cluster, have been carried out with the Advanced CCD Imaging Spectrometer (ACIS) on board Chandra X-Ray Observatory. We report the detection of two X-ray sources from the Arches cluster embedded within a bath of diffuse X-ray emission extending beyond the edge of the …
