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…
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…
Comparing accretion disk profiles of Bogush-Galt'sov naked singularity and Kerr black hole
R. Kh. Karimov, R. N. Izmailov, A. A. Potapov +1
It is well known that the Einstein-scalar system of general relativity can in principle yield non-unique exact spinning naked singularities, which lead to unique Kerr black hole wh…
Testing generalized spacetimes for black holes using the Hod function representation of the hoop conjecture
K. K. Nandi, R. N. Izmailov, R. Kh. Karimov +3
The hoop conjecture, due to Thorne, is a fundamental aspect of black holes in classical general relativity. Recently, generalized classes of regular spherically symmetric static bl…
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…
