Aims.We search for ultra luminous X-ray source (ULXs) radio counterparts located in nearby galaxies in order to constrain their physical nature.
Methods.Our work is based on a systematic cross-identification of the most recent and extensive available ULX catalogues and archival radio data.
Results.A catalogue of 70 positional coincidences is reported. Most of them are located within the galaxy nucleus. Among them, we find 11 new cases of non-nuclear ULX sources with possibly associated radio emission.
