Particle motion around generic black holes coupled to non-linear electrodynamics
Jaroslav Vrba, Ahmadjon Abdujabbarov, Arman Tursunov +2
We study spherically symmetric magnetically charged generic black hole solutions of general relativity coupled to non-linear electrodynamics (NED). For characteristic values of the…
A toy model for a baby universe inside a black hole
Hrishikesh Chakrabarty, Ahmadjon Abdujabbarov, Daniele Malafarina +1
We present a dynamical toy model for an expanding universe inside a black hole. The model is built by matching a spherically symmetric collapsing matter cloud to an expanding Fried…
Boosted Kerr black hole in the presence of plasma
Carlos A. Benavides-Gallego, Ahmadjon Abdujabbarov
In this work, we obtain the deflection angle for a boosted Kerr black hole in the weak field approximation using the optics in a curved spacetime developed by J.L. Synge in 1960. W…
Gravitational lensing around Kehagias-Sfetsos compact objects surrounded by plasma
Sudipta Hensh, Ahmadjon Abdujabbarov, Jan Schee +1
We study the optical properties of the Kehagias-Sfetsos (KS) compact objects, characterized by the "Hořava" parameter , in the presence of plasma, considering its homoge…
Black hole mimicker hiding in the shadow: Optical properties of the -metric
Askar B. Abdikamalov, Ahmadjon A. Abdujabbarov, Dimitry Ayzenberg +3
Can the observation of the "shadow" allow us to distinguish a black hole from a more exotic compact object? We study the motion of photons in a class of vacuum static axially-symme…
Charged particle motion around a quasi-Kerr compact object immersed in an external magnetic field
Bakhtiyor Narzilloev, Ahmadjon Abdujabbarov, Cosimo Bambi +1
We explore the electromagnetic fields around a quasi-Kerr compact object assuming it is immersed in an external asymptotically uniform magnetic field. Using the Wald method, compon…
