Abstract: We discuss the problem of the limit on the accretion rate onto a black hole. To understand the observed spectral features of potentially supercritical accretion flows (accretion above the classical Eddington limit) in ultraluminous X-ray sources (ULX) and active galactic nuclei (AGN), we calculate spectral energy distributions (SEDs) of highly accreting black holes with masses in the range of 10 to 108 M, surrounded by an accretion disk and an extended atmosphere. Continuum features like the peak intensity of thermal emission at 1 keV as well as the iron K line complex between 6 keV and 8 keV are analyzed for various inclination angles, central masses and accretion rates. Both line and continuum emission depend considerably on these parameters, offering a chance to estimate these often unknown quantities of observed accretion disk systems.
