Abstract
We present a systematic search for radio counterparts to Ultraluminous X‐ray (ULX) source candidates based on a cross‐correlation of the Swartz et al. (2004) ULX catalogue based on Chandra data and the FIRST radio survey. We find seven cases of conspicuous peaks of radio emission that could be associated to ULX sources. Among these seven ULX radio candidates, three X‐ray sources are located within 5″of the FIRST radio peaks. These three cases are shown and discussed individually (� 2011 WILEY‐VCH Verlag GmbH & Co.
