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…
Spherical orbits around Kerr-Newman and Ghosh black holes
A. S. Alam, L. C. Andaru, B. N. Jayawiguna +1
We conduct a comprehensive study on spherical orbits around two types of black holes: Kerr-Newman black holes, which are charged, and Ghosh black holes, which are nonsingular. In t…
Strong lensing and shadow of Ayon-Beato-Garcia (ABG) nonsingular black hole
H. S. Ramadhan, M. F. Ishlah, F. P. Pratama +1
We study nonsingular black holes viewed from the point of view of Ayon-Beato-Garcia (ABG) nonlinear electrodynamics (NLED) and present a complete study of their corresponding stron…
Thermodynamics of EiBI-AdS black holes with global monopole
A. M. Kusuma, B. N. Jayawiguna, H. S. Ramadhan
It is well-known that black hole can be endowed with topological charge coming as a result of phase transition(s) in the early universe. It has also recently been revealed that suc…
Bound orbits around charged black holes with exponential and logarithmic electrodynamics
A S. Habibina, B. N. Jayawiguna, H. S. Ramadhan
We present exact black hole solutions endowed with magnetic charge coming from exponential and logarithmic nonlinear electrodynamics (NLED). Classically, we analyze the null and ti…
Charged black holes in higher-dimensional Eddington-inspired Born-Infeld gravity
Byon N. Jayawiguna, Handhika S. Ramadhan
We study static (electrically)-charged solutions of Eddington-inspired Born-Infeld (EiBI) theory of gravity in general -dimensional spacetime. We consider both linear (Maxwell)…
Gravitational field of global monopole within the Eddington-inspired Born-Infeld theory of gravity
Reyhan D. Lambaga, Handhika S. Ramadhan
Within the framework of the recent Eddington-inspired Born-Infeld (EiBI) theory we study gravitational field around an global monopole. The solution also suffers from the d…
