A Cosmological Scenario with Rotation

Abstract

A Bianchi type IX cosmological model with expansion and rotation has been constructed in the framework of general relativity. The model comprises the Friedmannian stages of the Universe evolution including the subsequent transition to accelerated exponential expansion observed nowadays. The gravitational field sources of the model are ultrarelativistic matter, dust and a comoving anisotropic rotating dark energy. The possibility of detecting the cosmological rotation by astrophysical observations is discussed.
