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…
Noncommutative Regge-Wheeler potential: some nonperturbative results
Nikola Herceg, Tajron Jurić, A. Naveena Kumara +2
We study the gravitational perturbation theory of black holes in noncommutative spacetimes with noncommutativity of the type and $[φ\stackrel…
Fermion quasinormal modes on modified RN background
Nikola Herceg, Nikola Konjik, A. Naveena Kumara +1
Noncommutative (NC) geometry may open an alternative route to quantum gravity. We study the influence of the spacetime noncommutativity on the Dirac quasinormal modes in the modifi…
Noncommutative Quasinormal Modes and the Violation of Isospectrality
Nikola Herceg, Tajron Jurić, A. Naveena Kumara +2
We explore quasinormal modes (QNMs) of the Schwarzschild black hole under a noncommutative (NC) deformation of spacetime, constructed via a Drinfeld twist formalism. In this approa…
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…
Gravitational probe of quantum spacetime
Nikola Herceg, Tajron Jurić, Andjelo Samsarov +2
A quest for phenomenological footprints of quantum gravity is among the central scientific tasks in the rising era of gravitational wave astronomy. We study gravitational wave dyna…
