A Quantum-Gravity-Motivated GUP Effective Metric

M. H. Al Ghifari, M. F. Fauzi, A. Rohim +3

Recent critiques have addressed certain aspects of the generalized uncertainty principle (GUP) effective metric (Ong 2023). This study presents a scale-dependent quadratic GUP effe…

Astrophysical environment around a black hole in the braneworld and its optical signatures

M. F. Fauzi, A. O. Latief, A. Sulaksono

We investigate the impact of braneworld theory on the astrophysical environment surrounding a black hole. The black hole is sourced by localized matter from the bulk, which could d…

Two descriptions of dark matter around a black hole: photon sphere, shadow, and lensing

M. F. Fauzi, H. S. Ramadhan, A. Sulaksono

We examine the observational discrepancies of two widely used models describing anisotropic (dark) matter distributions around a black hole, focusing on their photon spheres, shado…

Comment on "Strong lensing and shadow of Ayon-Beato-Garcia (ABG) nonsingular black hole"

M. Fahmi Fauzi

A recent article (Ramadhan et al. Eur Phys J C 83:465, 2023) suggested that the Sagittarius A* black hole cannot be modeled by an Ayon-Beato-Garcia regular black hole due to the in…

Horizonless star based on regular black hole with finite radius and its observational signatures

M. F. Fauzi, B. N. Jayawiguna, H. S. Ramadhan +1

The horizonless configuration of regular black holes has recently attracted attention as a model for ultracompact stars. In this paper, we propose a new class of regular black hole…

Imaging the destruction of a rotating regular black hole

M. F. Fauzi, H. S. Ramadhan, A. Sulaksono +1

A regular black hole, unconstrained by the weak cosmic censorship conjecture, can exceed its critical spin limit and transition into a superspinar. In this paper, we investigate th…
