Black Hole Shadows Constrain Extended Gravity
V. Prokopov, S. Alexeyev, O. Zenin
The first images of black hole shadows open new possibilities to constrain modern extended gravity theories. We present the method of shadow background calculation for black hole s…

Shadows from spinning black holes in extended gravity
S. O. Alexeyev, V. A. Prokopov
When the the shadow image of a supermassive black hole in the center of M87 was obtained a new era in the observational astrophysics began. The resolution improvement would allow t…

Phenomenological Extension for Tidal Charge Black Hole
S. O. Alexeyev, B. N. Latosh, V. A. Prokopov +1
A simple phenomenological extension of the black hole solution with tidal charge is proposed. Empirical data on the Sgr A* is consistent with the suggested metric which serves as a…
