Strong gravitational lensing around Kehagias-Sfetsos compact objects surrounded by plasma
Sudipta Hensh, Jan Schee, Ahmadjon Abdujabbarov +1
We present the analysis how Hořava gravity and plasma influence the strong lensing phenomena around Kehagias-Sfetsos (KS) black holes. Using the semi-analytical Bozza method of str…
Dynamics and Fundamental Frequencies of Test Particles Orbiting Kerr-Newman-NUT-Kiselev Blacks Hole in Rastall Gravity
Bakhtiyor Narzilloev, Ibrar Hussain, Ahmadjon Abdujabbarov +2
The spacetime properties in the exterior of the Kerr-Newman-NUT-Kiselev black hole in the Rastall theory of gravity, through particle dynamics are investigated with the aim to find…
Circular motion of particle around Schwarzschild-MOG black hole
Madina Boboqambarova, Bobur Turimov, Ahmadjon Abdujabbarov
In this note, we have analyzed the circular motion of test particles around the Schwarzschild-MOG black hole. First, we have studied the shadow cast by the spherical symmetric blac…
Axion-plasmon or magnetized plasma effect on an observable shadow and gravitational lensing of a Schwarzschild black hole
Farruh Atamurotov, Kimet Jusufi, Mubasher Jamil +2
In this paper, we study the influence of the axion-plasmon, as proposed in (Phys. Rev. Lett. 120, 181803 (2018)) on the optical properties of the Schwarzschild black hole. Our aim…
Motion of Particles and Gravitational Lensing Around (2+1)-dimensional BTZ black holes in Gauss-Bonnet Gravity
Bakhtiyor Narzilloev, Sanjar Shaymatov, Ibrar Hussain +3
We study motion of test particles and photons in the vicinity of (2+1) dimensional Gauss-Bonnet (GB) BTZ black hole. We find that the presence of the coupling constant serves as an…
Effects of gravitational lensing on neutrino oscillation in -spacetime
Hrishikesh Chakrabarty, Debasish Borah, Ahmadjon Abdujabbarov +2
We study the effects of gravitational lensing on neutrino oscillations in the -spacetime which describes a static, axially-symmetric and asymptotically flat solution of the Eins…
