Black Hole Shadows Modelling in Extended gravity: Rotation Accounting and coupled effects
Stanislav Alexeyev, Oleg Zenin, Artem Baiderin
Using an improved version of the Newman-Janis algorithm, we obtain metrics of rotating black holes for a set of extended gravity theories that extend general relativity in differen…

Extended Gravity and Black Hole Shadows: Rotation Accounting
Stanislav Alexeyev, Oleg Zenin, Artem Baiderin
We obtain black hole rotating solutions for Horndesky theory (specific partial case), bumblebee model and Gauss-Bonnet scalar gravity using the specially improved Newman-Janis algo…

Non-local gravitational corrections in black hole shadow images
Stanislav Alexeyev, Artem Baiderin, Alexandra Nemtinova +1
With the help of Newman-Janis method new spinning black hole (BH) solution for a non-local gravity model was obtained. We show how to account the quantum gravitational correction p…
