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…
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…
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…
