A study is showing that higher redshift quasars emit more and more above their Eddington limit. How is this possible? Shouldnt this be causing the accretion disk to fly apart?

the study tries to give an explantion .
it has been known for a while that the Eddington Limit(Le) can be exceeded for periods of time..
but recall that the Le is a hypthetical limit based on the presumption that all the material is ionized hydorgen and all the material is accreted uniformally.
