Dark Energy Accretion onto black holes in a cosmic scenario

Understand

In this paper we study the accretion of dark energy onto a black hole in the cases that dark energy is equipped with a positive cosmological constant and when the space-time is described by a Schwarzschild-de Sitter metric.

• It is shown that, if confronted with current observational data, the results derived when no cosmological constant is present are once again obtained in both cases.
