Description
Ultra Luminous X-ray Sources (ULXs) are extragalactic X-ray point
sources with L_X ˜ 10^39-10^41 erg s^-1 discovered in the 80s with
the Einstein satellite and confirmed as black hole X-ray binaries during
the last decade. The nature of the compact object is highly
controversial. They could be super-Eddington stellar-mass black holes or
intermediate mass black holes. Deriving dynamical masses of the
brightest ULXs, which can be done with OSIRIS, is the only way to find
out the nature of the compact object.
