HBAR entropy of Infalling Atoms into a GUP-corrected Schwarzschild Black Hole and equivalence principle
Ali Övgün, Reggie C. Pantig
In this work, we have investigated the phenomenon of acceleration radiation exhibited by a two-level atom freely falling into a Generalized Uncertainty Principle (GUP)-corrected Sc…
Traversable Wormholes in Einstein-Euler-Heisenberg Gravity: Geometry, Energy Conditions, and Gravitational Lensing
Phongpichit Channuie, Allah Ditta, Narakorn Kaewkhao +1
In this study, we investigate traversable wormholes within the framework of Einstein-Euler-Heisenberg (EEH) nonlinear electrodynamics. By employing the Einstein field equations wit…
New Black Hole Solutions of Second and First Order Formulations of Nonlinear Electrodynamics
Yosef Verbin, Beyhan Pulice, Ali Övgün +1
Inspired by the so-called Palatini formulation of General Relativity and of its modifications and extensions, we consider an analogous formulation of the dynamics of a self-interac…
Geodesics, accretion disk, gravitational lensing, time delay, and effects on neutrinos induced by a non-commutative black hole
A. A. Araújo Filho, N. Heidari, Ali Övgün
This paper explores gravitational phenomena associated with a non-commutative black hole. Geodesic equations are derived, and a thin accretion disk is analyzed to model the black h…
Spacetime-curvature induced uncertainty principle: linking the large-structure global effects to the local black hole physics
Reggie C. Pantig, Gaetano Lambiase, Ali Övgün +1
This paper links the advanced formulation of the Generalized Uncertainty Principle, termed the Asymptotic Generalized Extended Uncertainty Principle (AGEUP), to the corpuscular fra…
Properties of an axisymmetric Lorentzian non-commutative black hole
A. A. Araújo Filho, J. R. Nascimento, A. Yu. Petrov +2
In this work, we start by examining a spherically symmetric black hole within the framework of non-commutative geometry and apply a modified Newman-Janis method to obtain a new rot…
Probing Schwarzschild-like Black Holes in Metric-Affine Bumblebee Gravity with Accretion Disk, Deflection Angle, Greybody Bounds, and Neutrino Propagation
G. Lambiase, L. Mastrototaro, Reggie C. Pantig +1
In this paper, we investigate Schwarzschild-like black holes within the framework of metric-affine bumblebee gravity. We explore the implications of such a gravitational setup on v…
Horizon-scale tests of gravity theories and fundamental physics from the Event Horizon Telescope image of Sagittarius A
Sunny Vagnozzi, Rittick Roy, Yu-Dai Tsai +12
Horizon-scale images of black holes (BHs) and their shadows have opened an unprecedented window onto tests of gravity and fundamental physics in the strong-field regime. We conside…
Light deflection by Damour-Solodukhin wormholes and Gauss-Bonnet theorem
Ali Övgün
In this paper, using the recent method proposed by Ono, Ishihara and Asada (OIA) who extend the idea of Gibbons and Werner to the stationary and axisymmetric case, we apply the Gau…
