Dyonic rotating cosmological black hole surrounded by quintessence
Abstract
In this work, we constructed a new metric describing a rotating cosmological black hole with electric and magnetic charges in the presence of quintessence dark energy, where the cosmological constant and quintessence are associated with external matter. Starting from a Schwarzschild-type metric and considering all energy contributions in the function f(r), we introduced rotation through the Newman--Janis algorithm using a unique and general complexification rule, avoiding possible ambiguities. Assuming that the metric satisfies the Einstein field equations with matter, we calculate the event horizon condition, the total stress--energy tensor Tμν, and the Kretschmann and Ricci scalars. We also analyze the influence of the cosmological constant Λ and quintessence parameter α on the event horizon and ergosphere. In the limit α→ 0, the scalar curvature differs from the vacuum result, R ≠ −4Λ, while the singularity region remains unchanged. Finally, we investigate the angular and rotational velocities of a test particle, as well as the energy conditions, through the energy density and pressures required for the existence of this black hole solution.
