Time Variability of Low Angular Momentum Flows Accreting onto Black   Holes: A Natural Mechanism For Radiation Flaring
  We present results from our magnetohydrodynamical simulations of accretion flows onto black holes. Our main focus is the interplay between inflows and related outflows. We consider applications of such flows to the Galatic center and low luminosity active galactic nuclei.
