Superradiance scattering off rotating Simpson-Visser black hole and its shadow in the non-commutative setting

Understand

We consider non-commutating Simpson-Visser spacetime and study the superradiance phenomena and the shadow cast by the back hole associated with this modified spacetime.

• We extensively study the different aspects of the black hole associated with the metric endowed with the corrections linked with non-commutative properties of spacetime.
• We study the superradiance effect, deviation of shape, size of the ergosphere, and the shadow of black hole in this extended situation and look into their variation taking different values Simpson-Visser parameter $\ell$ and non-commutative parameter $b$.
• We have made an attempt to constrain the parameter $\ell$ using the data available from the EHT collaboration for $M87^*$ black hole.
