Abstract Absorbing charged rotating (ACR) metric in de Sitter space and related energy-momentum tensor are derived. The ACR metric is very simple in advanced time coordinates. The ACR metric involves 8 independent parameters which are divided into two classes: (1) the mass M, charge Q, angular momentum per unit mass a, and cosmological constant Λ ; (2)∂M/∂v, ∂²M/∂v², ∂Q/∂v, and ∂²Q/∂v². The non-stationary part of the energy-momentum tensor is positive definite everywhere.
