On Propagation of Light-Ray and Sagnac Effect in Kerr-Newman-Nut Spacetime

Authors: Bobur Turimov, Akhror Mamadjanove, Farruh Atamurotova, Kholida Boymurodova

The paper explores the light-ray propagation and Sagnac effect in Kerr-Newman-NUT spacetime. It has been analyzed the spacetime curvature structure of these solutions and represented that the Kerr-Newman-NUT spacetime is one of the exact analytical solutions for rotating regular black holes. The area of the horizon and ergosphere of the black hole has been explicitly derived. The electromagnetic feature of the Kerr-Newman-NUT black hole has been also discussed. The effect of the NUT parameter in capture cross-section of the photon by the black hole so-called the shadow black hole has been analyzed. Finally, the Sagnac effect in the Kerr-Newman-NUT space has explicitly discussed.
