Dirac Quasinormal Modes in Noncommutative Reissner-Nordström Black Holes
Nikola Herceg, Nikola Konjik, A. Naveena Kumara +1
Noncommutative (NC) geometry provides a novel approach to probe quantum gravity effects in black hole spacetimes. This work explores Dirac quasinormal modes (QNMs) of a deformed Re…

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…

Towards gravitational QNM spectrum from quantum spacetime
Nikola Herceg, Tajron Jurić, Andjelo Samsarov +1
The effective potential for the axial mode of gravitational wave on noncommutative Schwarzschild background is presented. Noncommutativity is introduced via deformed Hopf algebra o…
