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…
Shadow images of regular black hole with finite boundary
M. F. Fauzi, H. S. Ramadhan, A. Sulaksono
Regular black hole is one of the bottom-up solutions designed to eliminate the singularity at the center of black holes. Its horizonless solution has gained interest recently to mo…
Anisotropic gravastar as horizonless regular black hole spacetime and its images illuminated by thin accretion disk
M. F. Fauzi, H. S. Ramadhan, A. Sulaksono
A connection between regular black holes and horizonless ultracompact objects was proposed in~\cite{Carballo-Rubio:2022nuj}. In this paper, we construct a model of a horizonless co…
