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…
Accretion Flow onto Ellis-Bronnikov Wormhole
R. M. Yusupova, R. Kh. Karimov, R. N. Izmailov +1
Study of accretion onto wormholes is rather rare compared to that onto black holes. In this paper, we consider accretion flow of cosmological dark energy modeled by barotropic flui…
Thin accretion disks around a Schwarzschild acoustic black hole
R. M. Yusupova, R. N. Izmailov, R. Kh. Karimov
We investigate the properties of a thin accretion disk in the Novikov-Thorne framework around a Schwarzschild acoustic black hole characterized by a nonzero background fluid four-v…
