We investigated spectral nature as well as counterparts in the XRBs in IR, Optical and UV bands. Combined X-ray luminosity function of the resolved point sources within optical D25 of the target galaxy is well described by a power law with a break at 2.5$\times$10$^{38}$ erg s$^{-1}$, corresponding to the Eddintong limit of a 1.4 Msun neutron star. The X-ray color-color plot derived for the resolved sources enabled us to classify them as LMXBs, HMXBs, ULXs and field AGNs. The cumulative X-ray spectroscopy of the discrete sources within the optical D25 region is well constrained by a power law with the photon index of 1.45. Spatially resolved spectral analysis of the hot gas in this system exhibits structure in the temperature as well as metallicity. We also report the contribution of the XRBs to the total X-ray luminosity of the target galaxy. |
