Noncommutative geometry inspired charged black holes
Abstract
We find a new, noncommutative geometry inspired, solution of the coupled EinsteinMaxwell field equations describing a variety of charged, selfgravitating objects, including extremal and nonextremal black holes. The metric smoothly interpolates between de Sitter geometry, at short distance, and ReissnerNordstrøm geometry far away from the origin. Contrary to the ordinary ReissnerNordstrøm spacetime there is no curvature singularity in the origin neither “naked” nor shielded by horizons. We investigate both Hawking process and pair creation in this new scenario.
