Charged noncommutative geometry inspired stringy black hole

Abstract

Motivated by string theory as an inspiring source for both the black hole solution and noncommutative geometry, we constructed a new solution of a noncommutative charged black stringy black hole solution. The noncommutativity effect appears to cure the singularity problem for this solution. Furthermore, we studied the optical behavior through the shadow by calculating the shadow radius, and it appeared that the shape is perfectly circular with a size depending on the black hole parameters. More precisely, the increase of each parameter, namely the magnetic charge Q and noncommutative parameter [Formula: see text], drives a reduction of the shadow size.
