Scientific paper

Within the D25 ellipse of M83, 21 X-ray sources are detected with the ROSAT HRI. A variable super-Eddington (3.8×1039 erg s-1) X-ray source is found to coincide with a faint, extended optical counterpart. Based on the multiwavelength characteristics, the source most likely represents a massive (~30 Msolar) accreting black hole binary, located in a compact HII region or in a globular cluster in M83. We also detect two luminous (3.7 and 6.7×1038 erg s-1) previously unknown supernova remnant candidates, located in extended Hα emission complexes and coinciding with compact 6 cm and 20 cm radio sources. .
