Black hole masses and accretion states in ULXs
We summarize indirect empirical arguments used for estimating black hole (BH) masses in ultraluminous X-ray sources (ULXs). The interpretation of the X-ray data is still too model-dependent to provide tight constraints, but masses ?100M? seem the most likely. It is getting clearer that ULXs do not s...
