Description
SS433 is the only known persistent supercritical accretor, it may
be very important for understanding ultraluminous X-ray sources (ULXs)
located in external galaxies. We describe main properties of the SS433
supercritical accretion disk, jets and its nebula W50.
Basing on observational data of SS433 and published 2D simulations of
supercritical accretion disks we estimate parameters of the funnel in
the disk/wind of SS433 and discuss formation of the jets and the nebula.
We review properties of the ULXs and compare them with SS433/W50.
We present results of 3D-spectroscopy of nebulae around several ULXs
located in galaxies at 3-10 Mpc distances. The nebulae are found to be powered by
their central black holes.
