Abstract:
We obtained analytical expression for shadows around supermassive black
holes for a wide class of spherically symmetric black hole solutions,
such a Reissner – Nordstrom with a tidal charge, dyonic Reissner –
Nordstrom – (anti) de-Sitter, black hole in Horndeski gravity.
Therefore, observations of such shadows could be indicator of an
alternative theory of gravity. We also found properties of shadows
around Kerr black holes. which could be observed in the future with the
Event Horizon Telescope and projected space-ground interferometer
Millimetron.
