Shadow of Non-singular Rotating Magnetic Monopole in Perfect Fluid Dark matter

TL;DR

This paper investigates how the shadow and emission properties of a rotating Bardeen black hole are affected by perfect fluid dark matter, considering parameters like spin, magnetic charge, and dark matter influence.

Contribution

It presents a novel analysis of the shadow shape and emission rate of a rotating Bardeen black hole in the presence of perfect fluid dark matter, highlighting parameter effects.

Findings

Shadow size and shape are influenced by dark matter, spin, and magnetic charge.

Emission rate increases with dark matter parameter, decreases with magnetic charge and spin.

Dark matter significantly alters observable black hole features.

Abstract

Bardeen proposed a gravitationally collapsing magnetic monopole black hole solution which is free of singularity. In this article, we have studied the size and shape of the rotating Bardeen blackhole shadow in presence of perfect fluid dark matter. we have discussed how the parameters such a spin, magnetic monopole charge and influence of dark matter affects the shadow of our blackhole. The apparent shape of the blackhole was studied by using two observables, the radius Rs and the distortion parameter R_s. Further the blackhole emission rate is also studied, we found out that for rotating Bardeen in PFDM ,For a constant monopole charge, the emission rate increases with increase in dark matter parameter, the emission rate decreases with increase in magnetic charge and spin.
