Can accretion properties distinguish between a naked singularity, wormhole and black hole?
R. Kh. Karimov, R. N. Izmailov, A. A. Potapov +1
We first advance a mathematical novelty that the three geometrically and topologically distinct objects mentioned in the title can be exactly obtained from the Jordan frame vacuum…
String effect on the relative time delay in the Kerr-Sen black hole
R. N. Izmailov, R. Kh. Karimov, A. A. Potapov +1
A well known solution of heterotic string theory is the spinning Kerr-Sen black hole (KSBH) characterized by a string parameter . Kerr black hole is recovered at . The purp…
Accretion disks around the Gibbons-Maeda-Garfinkle-Horowitz-Strominger charged black holes
R. Kh. Karimov, R. N. Izmailov, Amrita Bhattacharya +1
It seems surprising that the emissivity properties of the accretion disk (\textit{à la} Page and Thorne) surrounding the Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) black h…
Vacuum Brans-Dicke theory in the Jordan and Einstein frames: can they be distinguished by lensing?
R. N. Izmailov, R. Kh. Karimov, A. A. Potapov +1
Vacuum Brans-Dicke theory can be self-consistently described in two frames, the Jordan frame (JF) and the conformally rescaled Einstein frame (EF), the transformations providing an…
Upper limit on NUT charge from the observed terrestrial Sagnac effect
A. Kulbakova, R. Kh. Karimov, R. N. Izmailov +1
The \textit{exact} Sagnac delay in the Kerr-Taub-NUT (Newman-Unti-Tamburino) spacetime is derived in the equatorial plane for non-geodesic as well as geodesic circular orbits. The…
Accretion disk around the rotating Damour-Solodukhin wormhole
R. Kh. Karimov, R. N. Izmailov, K. K. Nandi
A new rotating generalization of the Damour-Solodukhin wormhole (RDSWH), called Kerr-like wormhole, has recently been proposed and investigated by Bueno \textit{et al} for echoes i…
