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…
LoveCurvature: Exploring compact stars' quasi-universal relation with curvature scalars
M. D. Danarianto, A. Sulaksono
We investigate quasi-universal relations in neutron stars linking standard observables, such as tidal deformability () and normalized moment of inertia (), with normali…
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…
The Milky Way and M31 rotation curves in Yukawa gravity: phenomenology and Bayesian analysis
Davendra S. Hassan, M Dio Danarianto, Anto Sulaksono
Yukawa gravity provides a generalized framework for modeling gravity modification. We investigate the rotation curve profiles of spiral galaxies under Yukawa-like theories governed…
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…
