Spectral Bifurcations in Quasinormal Modes of Regular BTZ Black Holes
Kartheek Hegde, Tajron Jurić, A. Naveena Kumara
We study the quasinormal spectrum of massless scalar fields propagating on a family of regular BTZ black holes arising from an infinite tower of dimensionally regularized Lovelock…
Noncommutative dyonic black holes sourced by nonlinear electromagnetic fields
Ana Bokulić, Filip Požar
We introduce the first-order noncommutative (NC) corrections to the general nonlinear electrodynamics (NLE) Lagrangian depending on two electromagnetic invariants. The NC deformati…
Conundrum of regular black holes with nonlinear electromagnetic fields
Ana Bokulić, Tajron Jurić, Ivica Smolić
The search for regular black holes with nonlinear electromagnetic fields has sprouted numerous candidates, each exhibiting certain virtues but often accompanied by significant draw…
Primordial black hole formation in k-inflation models
Neven Bilić, Dragoljub D. Dimitrijević, Goran S. Djordjevic +2
The local primordial density fluctuations caused by quantum vacuum fluctuations during inflation grow into stars and galaxies in the late universe and, if they are large enough, al…
Euclidean Thermodynamics and Lyapunov Exponents of Einstein-Power-Yang-Mills AdS Black Holes
Karthik R., Dillirajan D., K. M. Ajith +3
We study the thermodynamics of Einstein-Power-Yang-Mills AdS black holes via the Euclidean path integral method, incorporating appropriate boundary and counterterms. By analyzing u…
A scaling invariance of the perturbations in -inflation models
Neven Bilić, Dragoljub D. Dimitrijević, Goran S. Djordjevic +2
We study the background and perturbations in -essence inflation models and show that a general -essence exhibits a simple scaling property. In particular, we study two classe…

Filip Požar
In this letter we introduce the noncommutative geometry into the standard Einstein-Hilbert-Maxwell action via the Drinfeld twist and solve the equation…
Perturbations of Black Holes Surrounded by Anisotropic Matter Field
Sagar J C, Karthik R, Katheek Hegde +3
Our research aims to probe the anisotropic matter field around black holes using black hole perturbation theory. Black holes in the universe are usually surrounded by matter or fie…
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…
Hexadecapole at the heart of nonlinear electromagnetic fields
Ana Bokulić, Tajron Jurić, Ivica Smolić
In classical Maxwell's electromagnetism, monopole term of the electric field is proportional to , while higher order multipole terms, sourced by anisotropic sources, fall-o…
Constant-roll inflation with tachyon field in the holographic braneworld
Marko Stojanovic, Neven Bilic, Dragoljub D. Dimitrijevic +2
We study inflation driven by the tachyon field in the holographic braneworld by assuming the second slow-roll parameter is constant. The parameter can be either defined by…

Ana Bokulić, Edgardo Franzin, Tajron Jurić +1
Nonlinear extensions of classical Maxwell's electromagnetism are among the prominent candidates for theories admitting regular black hole solutions. A quest for such examples has b…

We study inflation in a model with constant second slow-roll parameter . In this case, the Hubble expansion rate equation has analytical solutions describing four possible, nont…
Emergent diffeomorphism invariance in toy models
Hrvoje Nikolic
Conceptual difficulties in semiclassical and quantum gravity arise from diffeomorphism invariance of classical general relativity. With a motivation to shed some light on these dif…
Noncommutative Yang model and its generalizations
S. Meljanac, S. Mignemi
Long time ago, C.N. Yang proposed a model of noncommutative spacetime that generalized the Snyder model to a curved background. In this paper we review his proposal and the general…
Analog Schwarzschild-like geometry in fluids with external pressure
Neven Bilic
We study acoustic geometry in fluids with external pressure. In particular, we examine the conditions under which the acoustic metric mimics a Schwarzschild-like metric. We demonst…
Submarine paradox softened
Hrvoje Nikolic
In Supplee's submarine paradox, a naive argument based on Lorentz contraction leads to a contradiction that a fast submarine should sink in the water's reference frame but float in…

Athanasios Chatzistavrakidis, Georgios Karagiannis, George Manolakos +1
We investigate physical implications of a gravitational analog of axion electrodynamics with a parity-violating gravitoelectromagnetic theta term. This is related to the Nieh-Yan t…

Nicolas R. Bertini, Neven Bilic, Davi C. Rodrigues
We consider an action for gravity that, in addition to the Einstein-Hilbert term, contains a function of the Ricci scalar and the Gauss-Bonnet invariant. The specific form of the f…
