Lorentz violation and noncommutative effect on superradiance scattering off Kerr-like black hole and on the shadow of it

Understand

We consider a Lorentz violating non-commutating Kerr-like spacetime and studied the superradiance effect and the shadow cast by the back hole.

• We extensively study the different aspects of the black hole associated with a generalized Kerr-like spacetime metric endowed with the corrections licked with Lorentz violation and non-commutativity effect jointly.
• We investigate the superradiance effect, deviation of shape, and size of the ergosphere, energy emission rate, and black hole shadow in this generalized situation and study their variation taking different admissible values of Lorentz violating parameter $l$ and non-commutative parameter $b$.
• The admissible range has been determined from the observation of the Event Horizon Telescope (EHT) collaboration concerning $M87_8$ astronomical black hole.
