Query: Lorentz violation and noncommutative effect on superradiance scattering
  off Kerr-like black hole and on the shadow of it   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. We observe that the
superradiance phenomena has a crucially depends on the parameter $l$ and $b$
apart from its dependence on $a$ which is linked to the spin of the black hole.
We also observe that with the increase in Lorentz violating parameter $l$, the
size of the black hole shadow increases, and with the increase in the
non-commutative parameter $b$, the size of the black hole decreases. We have
made an attempt to constrain parameters $b$ of a non-commutative Kerr-like
black hole using the observation available from the EHT collaboration, in the
same way, we put constrain on the Lorentz violating parameter $l$. This study
shows that black holes associated with non-commutative Kerr-like spacetime may
be a suitable candidate for an astrophysical black hole.
