Evolution of a Schwarzschild Black Hole in Phantom-like Chaplygin gas Cosmologies

Understand

In the classical relativistic regime, the accretion of phantom energy onto a black hole reduces the mass of the black hole.

• In this context, we have investigated the evolution of a Schwarzschild black hole in the standard model of cosmology using the phantom-like modified variable Chaplygin gas and the viscous generalized Chaplygin gas.
• The corresponding expressions for accretion time scale and evolution of mass have been derived.
• Our results indicate that mass of the black hole will decrease if the accreting phantom Chaplygin gas violates the dominant energy condition and will increase in the opposite case.
