After Radio and X-ray observations by previous teams, and after our Gemini and CAsLeo optical observations, three explanations are still consistent with the properties of the source Maddox 28 located outside the bulge in the main body of the nearby galaxy M83: 1) 0ne of the remaining black holes of the double nucleus but single black hole scenario in the core of M83 (D¶³az et al. 2006), i.e. a kick-o® black hole as predicted by several models but not observed yet in any merger case; 2) the ¯rst microquasar outside the milky way, i.e. M83 starburst disk environment could be harboring a detectable case of very massive binary star with superluminal jets; 3) the hypothesis of Maddox et al. might be con¯rmed, i.e. a radio galaxy at high redshift, for which the absence of redshifted lines in the spectral range we observed suggest it could be one of the largest radio structures known at high redshift.
