Abstract

This work aims to present some quantum aspects of a non-commutative (NC) gauge gravity formulation of a Schwarzschild-like black hole constructed via the Moyal twist ∂ t ∧ ∂ θ ∂ t ∧ ∂ θ . Particle creation is estimated for bosonic and fermionic fields using the quantum tunneling method, with divergent integrals treated through the residue prescription. Since the surface gravity is well defined for this configuration, the corresponding emission rates and evaporation lifetimes are also computed. In addition, previously reported results in the literature on gauge gravity Schwarzschild black holes are revisited. Finally, we infer constraints on the NC parameter Θ Θ from solar-system tests.
