How Dim Accreting Black Holes Could Be?
Marek A. Abramowicz, Igor V. Igumenshchev
Recent hydrodynamical simulations of radiatively inefficient black hole accretion flows with low viscosity have demonstrated that these flows differ significantly from those descri…

On the absence of winds in ADAFs
Marek A. Abramowicz, Jean-Pierre Lasota, Igor V. Igumenshchev
We show that recently published assertions that advection dominated accretion flows (ADAFs) require the presence of strong winds are unfounded because they assume that low radiativ…
