Ringdown of a black hole sourced by a Burkert-density effective anisotropic source
Yi Yang, Gaetano Lambiase, Ali Ovgun +2
We construct a static, spherically symmetric black hole spacetime sourced by an effective anisotropic matter distribution whose energy density follows the cored Burkert profile. Th…
Probing Quantum Gravity in Stellar Spacetimes: Phenomenological Insights
Reggie C. Pantig, Ali Ovgun, Gaetano Lambiase
We explore the weak-field phenomenology of a compact star spacetime modified by quantum gravitational corrections derived from the effective field theoretical (EFT) approach by Cal…
Entanglement saturation in quantum electrodynamics scattering processes
Massimo Blasone, Silvio De Siena, Gaetano Lambiase +2
We investigate the properties of quantum electrodynamics (QED) two-particle scattering processes when an arbitrarily sharp filtering of the outgoing particles in momentum space is…
Phenomenology of Schwarzschild-like Black Holes with a Generalized Compton Wavelength
Reggie C. Pantig, Ali Ovgun, Gaetano Lambiase
We investigate the influence of the generalized Compton wavelength (GCW), emerging from a three-dimensional dynamical quantum vacuum (3D DQV) on Schwarzschild-like black hole space…
Shadow and quasinormal modes of the rotating Einstein-Euler-Heisenberg black holes
Gaetano Lambiase, Dhruba Jyoti Gogoi, Reggie C. Pantig +1
The Einstein-Euler-Heisenberg (EEH) black hole model is an extension of classical black hole solutions in general relativity, incorporating quantum electrodynamics (QED) effects vi…
Weak field deflection angle and analytical parameter estimation of the Lorentz-violating Bumblebee parameter through the black hole shadow using EHT data
Gaetano Lambiase, Reggie C. Pantig, Ali Ãvgün
We explored how the Lorentz symmetry breaking parameter affects the Reissner-Nordstöm BH solution in the context of weak field deflection angle, and the black hole shadow.…
