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…

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…
