Accretion onto a quintessence contaminated rotating black hole: violating the lower limit for eta over s

Abstract Viscous accretion flow around a rotating supermassive black hole sitting in a quintessence tub is studied in this article. To introduce such a dark energy contaminated black hole’s gravitational force, a new pseudo-Newtonian potential is used. This pseudo-Newtonian force can be calculated i...
