Times of arrival (TOA) of signals in the Kerr-MOG black hole
G. Y. Tuleganova, R. N. Izmailov, R. Kh. Karimov +2
Modified gravity (MOG) theories are alternatives to general relativity (GR) that arose primarily from the need to explain the observed galactic flat rotation curves without invokin…
Can massless wormholes mimic a Schwarzschild black hole in the strong field lensing?
Ramil N. Izmailov, Eduard R. Zhdanov, Amrita Bhattacharya +2
Recent trend of research indicates that not only massive but also massless (asymptotic Newtonian mass zero) wormholes can reproduce post-merger initial ring-down gravitational wave…
Terrestrial Sagnac delay constraining modified gravity models
R. Kh. Karimov, R. N. Izmailov, A. A. Potapov +1
Modified gravity theories include gravity models that are usually constrained by the cosmological evolutionary scenario. However, it has been recently shown that th…
Mass decomposition of SLACS lens galaxies in Weyl conformal gravity
Alexander A. Potapov, Ramil N. Izmailov, Kamal K. Nandi
We study here, using the Mannheim-Kazanas solution of Weyl conformal theory, the mass decomposition in the representative subsample of early-type elliptical lens galaxies of t…
Revisiting perfect fluid dark matter: Observational constraints from our galaxy
Alexander A. Potapov, Guzel M. Garipova, Kamal K. Nandi
We revisit certain features of an assumed spherically symmetric perfect fluid dark matter halo in the light of the observed data of our galaxy
Stability and instability of Ellis and phantom wormholes: Are there ghosts?
Kamal K. Nandi, Alexander A. Potapov, Ramil Izmailov +2
It is concluded in the literature that Ellis wormhole is unstable under small perturbations and would decay either to the Schwarzschild black hole or expand away to infinity. While…
