SUMMARY:Ultraluminous Supersoft X-ray sources as super-critical accretion o
 nto stellar black holes
DESCRIPTION:Ultraluminous Supersoft X-ray sources as super-critical accreti
 on onto stellar black holes\nProf. Jifeng Liu\n\nWhile ultraluminous super
 soft X-ray sources (ULSs) bear features for intermediate mass black holes 
 or very massive white dwarfs possibly close to Chandrasekhar mass limit, o
 ur recent discovery of processing relativistic baryonic jets from a protot
 ype ULS in M81 demonstrate that they are not IMBHs or WDs, but black holes
  accreting at super-Eddington rates. This discovery strengthens the recent
  ideas that ULXs are stellar black holes with supercritical accretion, as 
 demonstrated in the case of M101 ULX-1, and provides a vivid manifestation
  of what happens when a black hole devours too much, that is, it will gene
 rate thick disk winds and fire out sub-relativistic baryonic jets along th
 e funnel as predicted by recent numerical simulations.
