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…

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…

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…

Hidden BPS states of electroweak monopole and a new bound estimate

A. Gunawan, H. S. Ramadhan, I. Prasetyo

Using the BPS Lagrangian method, we obtain a distinct set of Bogomolny equations for the Cho-Maison monopoles from the bosonic sector of a regularized electroweak theory. In the li…
