Ultraluminous X-ray sources in the first eROSITA survey I. Candidate catalogs

P. Weber, T. P. Roberts, S. Hämmerich +28

Ultraluminous X-ray sources (ULXs) are luminous non-nuclear X-ray point sources embedded in galaxies. Their luminosities exceeding 10^39 erg/s potentially require sub-Eddington acc…
