Özet

The X-ray and optical properties of seven ultraluminous X-ray Sources (ULXs) in the interacting galaxies NGC 4490/ 4485 were examined in this study. The XMM-Newton and Chandra archival data were used for X-ray analyses. To study the optical counterparts of ULXs, the Hubble Space Telescope, (HST) archival data were used. After the relative astrometric correction between the Chandra and HST images, bright optical counterpart candidates were found for three ULXs (X-4, X-6 and X-7).
