Ultra-luminous X-ray sources are accreting black holes that might represent strong evidence of the Inter-Mediate Mass Black Holes (IMBH), proposed to exist by theoretical studies but with no firm detection (as a class) so far.
In this talk I will present achievements that have been done in that direction and our new timing versus spectral results. I will discuss them in the framework of disc theory and provide some clues into the mass of these enigmatic objects.
