Near-horizon aspects of black holes in quantum spacetime
Nikola Herceg, Tajron Jurić, A. Naveena Kumara +2
We give a short introduction to the formalism of noncommutative (twisted) differential geometry that is used to derive the equations of motion for the gravitational perturbation of…

Noncommutative quasinormal modes of Schwarzschild black hole
Nikola Herceg, Tajron Jurić, A. Naveena Kumara +2
We study gravitational perturbations of the Schwarzschild metric in the context of noncommutative gravity. and noncommutativity are introduced through a Moyal twist of…

Entropy of black holes, charged probes and noncommutative generalization
Axel Hrelja, Tajron Jurić, Filip Požar
The brick wall model is a semi-classical approach to understanding the microscopic origin of black hole entropy. We outline the formalism for the brick wall model in arbitrary numb…
