“…Hence, the authors [68] should clarify about their solution. In addition, in [76] there is a derivation of the Kerr-Newman-AdS black hole solution surrounded by quintessence using the constraint from the first law of thermodynamics 3 and they perform that the solution in [77] (when κλ = 0) does not satisfy the weak energy condition. So, the solution given on Eq.…”

We demonstrate that Kerr/CFT duality can be extended to rotating charged black hole solution surrounded by quintessence in Rastall gravity. Since Rastall gravity can be considered as F (R, T ) = R + βT theory with a matter term, so the gravitational Lagrangian is similar to Einstein general relativity. In fact, the resulting central term is similar to the general relativity since T is only a trace of the matter term. We then show that the entropy from CFT of this black hole is equivalent with the Bekenstein-Hawking entropy with no correction related to the Rastall coupling constant. Moreover, when Rastall coupling constant κλ is switched off and a is approaching zero, we may extend the solution to 5D black hole solution. It is found that this solution contains twofold CFT duals that we call as Q-picture and P -picture. In both pictures, the CFT entropy reproduces exactly the Bekenstein-Hawking entropy for Reissner-Nordström black hole surrounded by quintessence. The results establish that, for all black holes surrounded by quintessence, the microscopic entropies of the dual CFTs agree with the Bekenstein-Hawking entropies.

“…Subsequently, by employing the Newman-Janis algorithm [42,43], Toshmatov et al further generalized the solution to the rotating case [44]. The corresponding Kerr-Newman-AdS solution was also obtained [45] by Xu et al by adopting a similar approach. The above solution was refined and fur-ther generalized by Wang et al [46] by scrutinizing the consistency regarding the black hole thermodynamics.…”

“…In reality, most black holes are not static, but rotating and possibly charged. In order to obtain the metric of the rotating black holes, the Newman-Janis algorithm has been extensively explored [44,45,47]. The algorithm is a complexification technique for deriving the rotating counterpart from a static solution of the Einstein field equations.…”

In this work, we study the optical properties of a class of magnetically charged rotating black hole spacetimes. The black holes in question are assumed to be immersed in the quintessence field, and subsequently, the resulting black hole shadows are expected to be modified by the presence of the dark energy. We investigate the photon region and the black hole shadow, and in particular, their dependence on the relevant physical conditions such as the state parameter of the quintessence, the angular momentum, and the magnitude of the magnetic charge. It is shown that the photon regions sensitively depend on the horizon structure and possess intricate features. Moreover, from the viewpoint of a static observer, we explore a few observables, especially those associated with the distortion of the observed black hole shadows.
