Non-extensive entropy signatures in compact star
B. N. Jayawiguna, M. H. Al Ghifari, A. Rohim +1
The non-extensive entropy models applied to the black-hole horizon are connected to the generalized Einstein--Hilbert action, , via the Wald entropy formalism. We demonstrate…
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…
Renormalization group improved black holes in non-commutative momentum-dependent spacetime geometry
Gema Ilham Baskara Darman, Ar Rohim, Anto Sulaksono
We investigate black holes (BHs) in momentum-dependent spacetime geometry and assess its quantum Reissner-Nordström (RN) consistency with the weak gravity conjecture (WGC). Quantum…
Ambiguity in matter sector for modified gravity involving and its implications to astrophysics and cosmology
B. N. Jayawiguna, A. Sulaksono
Matter density () and radial pressure () are often used as the matter Lagrangian density () because both are thermodynamically consistent and produce the sam…
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…
Photon Propagation and Black Hole Imaging in Kruglov Nonlinear Electrodynamics
H. S. Ramadhan, M. F. Fauzi, D. A. Witjaksana +1
We investigate the effective photon geometry associated with black holes in Kruglov nonlinear electrodynamics and its consequences for strong-field optical phenomena. This model co…
