Description
Recently we derived the first metric of a nonsingular black hole in the framework of generalized uncertainty principle (GUP) (https://arxiv.org/abs/2406.03909, https://arxiv.org/abs/2412.08004). Despite its over 30 years of history, no black hole metric was systematically derived in GUP due to issues in applying GUP to field theories. We applied the tricks used in LQG to this system and it made it possible to derive such a metric. Furthermore, I discuss how we used the Newman-Janis formalism to derive the rotating counterpart of this black hole, and compared it to the data from the Event Horizon Telescope to set a bound on the quantum parameters of the model.
