- W2960356981 abstract "We study both adiabatic and modified Chaplygin gas type accretion onto a type rotating black holes which are embedded in a quintessence universe and having an extra term depicting the quintessence effect in the lapse function of the corresponding black hole metric. Viscosity is neglected and the disk height is taken to be constant. Radial velocity and speed of sound gradients are found out. Infalling and outflow speed profiles are drawn and analysed. The quintessence equation of state parameter is treated to be the regulatory factor to control the effects of negative pressure produced by the quintessence. We follow the characteristics of the accretion and wind flow velocities around such a quintessence black hole. Changes in sound speed profiles through the accreting and winding are also observed. Along with these, the rotational parameter has shown importance as the effect of negative pressure is found to get catalysed by the entry of the spin of the black hole. We tally our result with observations of accretion or outflow phenomena near to different quasars." @default.
