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…
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…
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…
On a Class of Harko-Kovacs-Lobo Wormholes
R. Kh. Karimov, R. N. Izmailov, K. K. Nandi
The Harko, Kovács, and Lobo wormhole (HKLWH) metric contains two free parameters: one is the wormhole throat , and the other is a dimensionless deviation parameter with…
Can a regular black hole be observationally distinguished from singular black holes as spinning lens partner in PSR-BH binaries?
G. Y. Tuleganova, R. Kh. Karimov, R. N. Izmailov +1
To answer the question posed in the title, we consider a novel diagnostic, viz., the difference in the times of arrival (TOA) at the observer of two light rays that simultaneously…
Terrestrial Sagnac delay in scalar-tensor-vector-gravity
R. Kh. Karimov, R. N. Izmailov, K. K. Nandi
The scalar-tensor-vector-gravity (STVG), a prototype of modified gravity developed by Moffat, can correctly explain galaxy rotation curves, cluster dynamics, Bullet Cluster phenome…
