Effect of quintessence on the Nature of Kerr-newman blackhole shadow with clouds of strings

TL;DR

This paper investigates how quintessence and clouds of strings influence the shadow of a rotating charged blackhole, using the Newman-Janis algorithm to analyze its properties and photon orbits.

Contribution

It introduces a novel model of a rotating charged blackhole with clouds of strings and quintessence, analyzing its shadow and photon orbits for the first time.

Findings

Blackhole shadow varies with quintessence and string cloud parameters.

Effective potential and photon orbit stability are affected by surrounding fields.

Shadow plots demonstrate the impact of different variable profiles.

Abstract

In this paper we have took reissner nordstrom blackhole with cloud of strings and surrounds it with quintessence. we processed the metric through newman janis algorithm to get its rotating counterpart. the blackhole in study now is a roating charged blackhole with clouds of string surrounded by quintessence. we studied its nature of effective potential and unstable photon orbits. Finally we have plotted the blackhole shadow for various variable profiles.
