O článku:
Ultra-Luminous X-ray sources (ULXs) are accreting black holes for which their
X-ray properties have been seen to be different to the case of stellar-mass
black hole binaries. For most of the cases their intrinsic energy spectra
are well described by a cold accretion disc (thermal) plus a curved
high-energy emission components. The mass of the black hole (BH) derived
from the thermal disc component is usually in the range of 100-1000 solar
masses, which have led to the idea that this might represent strong evidence
of the Intermediate Mass Black Holes (IMBH), proposed to exist by
theoretical studies but with no firm detection (as a class) so far. Recent
theoretical and observational developments are leading towards the idea that
these sources are instead stellar-mass BHs accreting at an unusual
super-Eddington regime. In this paper we briefly describe the model SLIMULX
that can be used in XSPEC for the fit of thermal spectra of slim discs
around stellar mass BHs in the super-Eddington regime. This model
consistently takes all relativistic effects into account. We present the
obtained results from the fit of the X-ray spectra from NGC 5408 X—1.
