Description
Context. The nature of ultra-luminous X-ray (ULX) sources is still a
matter of debate. Studies of their counterparts in other spectral ranges
will help to clarify the nature of those sources. Aims: Our goal
was to identify and characterize the optical counterparts of five
sources catalogued as ULXs. Methods: We obtained optical imaging
and intermediate resolution spectroscopy of these optical counterparts.
Results: We demonstrate that five sources previously catalogued
as ULXs, two are foreground stars in our galaxy and three are background
active galactic nuclei.
