SUMMARY:What Are We Learning About Super-Eddington Accretion Disks Fro
 m Simulations?\, Astronomy Colloquium\, Prof. Chris Fragile\, College 
 of Charleston
DESCRIPTION:Accretion of gas onto black holes is one of the most impor
 tant processes shaping our Universe. Understanding extremely high rate
 s of accretion (dubbed `super-Eddington') is vital to explaining the c
 hallenging observation that supermassive black holes (SMBHs) are fully
  formed at redshifts >7. It is also important to understanding astroph
 ysical objects such as tidal disruption events (TDEs) and ultra-lumino
 us X-ray sources (ULXs). While we are able to perform observations of 
 super-Eddington accreting systems\, to understand them more fully\, we
  must turn to numerical studies. In this talk\, I will present the res
 ults of some recent super-Eddington disk simulations and discuss some 
 of the interesting things we are learning.<br>\n
