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…
