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…
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…
Damour-Solodukhin Wormhole as a Black Hole Mimicker: The Role of Observers' Location
K. K. Nandi, R. Kh. Karimov, R. N. Izmailov +1
It has been recently argued that in semi-classical gravity, a minimal 2-sphere is not a horizon but a tiny throat of a wormhole, such as the Damour--Solodukhin wormhole (DSWH), wit…
Gravitational time advancement effect in Bumblebee gravity for Earth bound systems
G. Y. Tuleganova, R. Kh. Karimov, R. N. Izmailov +3
This paper is a novel application of the new effect of gravitational time advancement or \textit{negative} time delay, first predicted for static black holes (spin ), that can…
