In my talk I will review our recent results related to the X-ray emission from the Galactic Center region, especially, the non-thermal emission of the Arches stellar cluster as observed with XMM-Newton and Chandra.

Recent studies based on XMM-Newton and SRG/ART-XC observations have reported an excess of X-ray emission per unit stellar mass in the Nuclear Stellar Disk (NSD) compared to regions farther from the Galactic Center. These results are based on hard X-ray measurements (4-12 keV) and studies of the Fe XXV emission line at 6.7 keV. In this work, we investigate the population of faint X-ray...
