Einstein Frame Regularization of the JNW Spacetime: From Brans-Dicke Singularity to Ellis Wormhole
A. Bhattacharya, R. N. Izmailov, R. Kh. Karimov
We propose a novel way to achieve the regularization of the JNW globally naked singularity sourced by the canonical Einstein minimally coupled scalar field (EMS). The key idea is t…
Stability regions of glued wormholes with massless Kim-Lee backreacted spacetimes as interior
G. F. Akhtaryanova, R. Kh. Karimov, R. N. Izmailov +1
Asymptotic zero Arnowitt-Deser-Misner (ADM) mass wormholes, such as the zero-mass traversable Ellis-Bronnikov wormhole, are of great interest for astrophysical applications such as…
Comments on the non-existence of unified hoop conjecture
A. Bhattacharya, R. N. Izmailov, R. Kh. Karimov
In a recent article, Hod [1] has concluded the non-existence, heretofore unnoticed, of a unified Thorne's hoop conjecture that holds for the quasi-local mass, $\mathcal{M}(r\leq R_…
Bondi Accretion onto a Damour-Solodukhin Wormhole
R. M. Yusupova, R. Kh. Karimov, A. Bhattacharya
The Damour-Solodukhin wormhole (hereinafter DSWH) is known to mimic Schwarzschild black hole (hereinafter SBH) horizon in some properties. To act as a mimicker, the DSWH parameter…
Galactic microlensing by backreacted massless wormholes
G. F. Akhtaryanova, R. Kh. Karimov, R. N. Izmailov +1
We study here a novel application of Kim \& Lee charged wormholes assuming them to be dark halo objects playing the role of lenses in the Galactic microlensing with source stars be…
On the Kalb-Ramond modified Lorentz violating hairy black holes and Thorne's hoop conjecture
K. K. Nandi, R. N. Izmailov, R. Kh. Karimov +1
Recently, a class of static spherically symmetric power law corrected Lorentz violating (LV) Schwarzschild black holes in the Kalb-Ramond model have been derived and studied in the…
