Probing scalarized wormholes through quasi-periodic oscillations and spinning particle dynamics
Asalkhon Alimova, Akbar Davlataliev, Farruh Atamurotov +3
We investigate the dynamics of test particles in a three-parameter scalarized wormhole spacetime within Einstein-scalar field theory. For spinless particles, we derive the orbital…
Cosmological Constraints on Minimal Cubic Galileon Models in Teleparallel Gravity
Akbar Davlataliev, Abdurakhmon Nosirov, Odil Yunusov +2
Cubic Galileon cosmological models provide a well-motivated framework for investigating late-time cosmic acceleration beyond the standard CDM paradigm. In this work, we study o…
Spherically-symmetrical vacuum solution in Freund-Nambu scalar-tensor gravity
Akbar Davlataliev, Bobur Turimov, Bobomurat Ahmedov +3
Scalar--tensor theories of gravity provide a natural extension of general relativity and may predict naked singularities as alternative compact objects. In this work, we investigat…
Effect of gravitational lensing around black hole in dark matter halo in the presence of plasma
Zhiyu Dou, Akbar Davlataliev, Mirzabek Alloqulov +4
This article is devoted to the investigation of the observational properties of the Schwarzschild black hole (BH) surrounded by a dark matter (DM) halo. Our study commences with a…
Long-lived quasinormal modes and asymptotic tails of regular Schwarzschild-like black holes in the presence of a magnetic field
Akbar Davlataliev, Bakhtiyor Narzilloev, Ibrar Hussain +2
We analyze the evolution of perturbations of a (charged) massive scalar field near a regular Simpson-Visser black hole, allowing for a non-zero external magnetic field. We show tha…
