Black hole shadows in M-theory scenarios

We study the shadows of four dimensional black holes in M-theory inspired models. first inspect influence M2-branes on such optical aspects for non-rotating solutions. In particular, we show that M2-brane number can control circular shadow size. This geometrical behavior is distorted rotating solutions exhibiting cardioid shapes certain moduli space regions. Implementing a rotation parameter, analyze deformations. Among others, recover behaviors large number. Investigating energy emission rate at high energies, find, well-defined approximation, associated peak decreases with Moreover, investigate possible connection observations (from Event Horizon Telescope or future devices) from particular compactification by deriving constraints light $M87^\star$ observational parameters.
