Can a light ray distinguish charge of a black hole in nonlinear electrodynamics?
Bobir Toshmatov, Bobomurat Ahmedov, Daniele Malafarina
It is a well-known fact that light rays do not follow the null geodesics of the space-time in nonlinear electrodynamics; instead, they follow the null geodesics of the so-called ef…
Dust collapse in 4D Einstein-Gauss-Bonnet gravity
Daniele Malafarina, Bobir Toshmatov, Naresh Dadhich
We consider gravitational collapse in the recently proposed 4D limit of Einstein-Gauss-Bonnet gravity. We show that for collapse of a sphere made of homogeneous dust the process is…
Motion of spinning particles in non asymptotically flat spacetimes
Bobir Toshmatov, Ozodbek Rahimov, Bobomurat Ahmedov +1
The assumption of asymptotic flatness for isolated astrophysical bodies may be considered an approximation when one considers a cosmological context where a cosmological constant o…
Spinning test particles in the spacetime
Bobir Toshmatov, Daniele Malafarina
We consider the motion of spinning particles in the field of a well known vacuum static axially-symmetric spacetime, known as metric, that can be interpreted as a generalizatio…
Quasinormal modes of magnetized black hole
Bobur Turimov, Bobir Toshmatov, Bobomurat Ahmedov +1
We investigate charged, massive scalar field around static, spherically symmetric black hole immersed into an external asymptotically uniform magnetic field . It is shown that f…
Harmonic oscillations of neutral particles in the -metric
Bobir Toshmatov, Daniele Malafarina, Naresh Dadhich
We consider a well-known static, axially symmetric, vacuum solution of Einstein equations belonging to Weyl's class and determine the fundamental frequencies of small harmonic osci…
