Abstract:
We search for ultra luminous X-ray source (ULXs) radio counterparts
located in nearby galaxies in order to constrain their physical
nature.
Our work is based on a systematic cross-identification of the most
recent and extensive available ULX catalogues and archival radio data.
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.

Note (1): ULX catalogues used as follows:
LB = Liu & Bergman, 2005, Cat. J/ApJS/157/59
LM = Liu & Mirabel, 2005, Cat. J/A+A/429/1125
CP = Colbert & Ptak, 2002, Cat. J/ApJS/143/25
Note (2): Comments as follows:
N = nuclear
QSO = quasar
HII = HII region
SNR = supernova remnant
E = non nuclear but extended
HNR = hypernova remnant
SSS = supersoft source
FRII = Fanaroff-Riley type II
N(2) = nuclear. Multiple coincidences with a single FIRST source
N(3) = nuclear. Very close to nucleus, but not exactly coincident
