Saeed Rastgoo: A GUP-inspired quantum black hole: the static and rotating cases, and their phenomenology

A106 (Physicum, University of Tartu)

Description

I present a new model of a black hole derived systematically from deforming the canonical algebra inspired by the generalized uncertainty principle (GUP). This model has two quantum parameters controlling the onset and strength of quantum gravity effects. I will discuss the geometry of both the static case and the rotating model derived using Newman-Janis algorithm. Furthermore, I show how a comparison of the shadow of the rotating model with parameters of Sgr A and M87 obtained by the Event Horizon Telescope sets a bound on the quantum parameters of the model.
