“…It is worth noting that the inclusion of the plasma medium introduces an additional parameter, k, in Eq. (45). For the numerical calculations, we consider different values for σ, ω q , Θ, and k. Subsequently, we determine the values of the photon sphere radius and impact parameters numerically by solving Eq.…”

“…In 2003, Kiselev derived a general form of the static spherically symmetric solutions of Einstein's equations and presented the line elements of electrically uncharged and charged black holes surrounded by quintessence matter [32]. Following this work, some other physicists obtained new solutions corresponding to various black holes of different properties in the presence of quintessence matter [33][34][35][36][37][38][39][40][41][42][43][44][45]. Recently, with the growing interest in black hole thermodynamics, we have observed studies discussing the influence of quintessence matter on the thermal quantities of black holes [46][47][48][49][50][51][52][53][54][55][56][57][58].…”

Recently, Campos et al investigated the quasinormal modes and shadows of noncommutative Schwarzschild black holes. Since we know that the quintessence matter surrounding black holes has important influences on the black hole quantities, we decided to handle the noncommutative Schwarzschild black hole embedded in quintessence matter. We first examined black hole's thermodynamics regarding the Hawking temperature, entropy, and specific heat functions. Then, we discussed phase transition and its stability. Next, we predicted the shadow images in the presence of plasma. After visualizing these results qualitatively, we calculated the quasinormal modes in WKB and Mashhoon approximations and we demonstrated the impacts of quintessence matter and noncommutative spacetime on the whole quantities.

“…In this analysis discussion of the horizons structure can be also found with a detailed investigation of the dynamics of both neutral and electrically charged test particles (with fundamental Keplerian frequencies and harmonic oscillations), photon spheres, scalars invariants, bolometric luminosity. Orbits and shadows for different parameter ranges are also studied in [26,30,[32][33][34][35][36][37][38][39][40][41][42][43], with a focus on the BH thermodynamics, phase transitions, causal structure, including the exploration of several extensions of the Kiselev solutions. A focus on the BHs thermodynamics is for example also in [44] and [45] with an investigation of the thermodynamic stability for Kerr-Newmann-NUT-Kiselev-AdS BH in Rastall gravitysee also [46].…”

Kiselev metric in the static and rotating form is widely used to test different aspects of the dark energy (DE) effects. We consider a DE Kiselev spacetime, predicting the reduction to the Kerr black hole (BH) solution under suitable conditions on the DE parameters and in this frame we study the effects of the dark energy on BHs and disks accretion. Elaborating a close comparison with the limiting vacuum Kerr spacetime, we focus on thick accretion disks around the central BH in the Kiselev solution, both co-rotating and counter-rotating with respect the central BH. We examine different aspects of BH accretion energetics by focusing on quantities related to the accretion rates and cusp luminosity, when considered the DE presence, related to the pure Kerr central BH. Our findings show that in these conditions heavy divergences with respect to the vacuum case are expected for the DE metrics. A known effect of the Kiselev metric is to lead to a false estimation the BH spin, we confirm this characteristic from the fluids dynamics analysis. Remarkably our results show that DE is affecting differently the accretion physics, and particularly the accretion rate, according to the fluid rotation orientation with respect to the central spinning attractor, leading in some cases to an under-estimation of the BH spin mass ratio. These contrasting aspects emerging in dependence on the fluids rotational orientation can be a distinguishing general DE feature which could lead to a revised observational paradigm where DE existence is considered.
