Abstract
In this paper, we explore the dynamics, thermodynamics, and observational features of the Bardeen–Kiselev black hole in AdS spacetime, motivated by the need to resolve curvature singularities and incorporate the influence of dark energy in strong gravity regimes. By coupling nonlinear electrodynamics with a quintessence field, the Bardeen–Kiselev–AdS solution provides a physically regular and rich framework to study modified black hole behavior. We first investigate the Hawking evaporation process and show that magnetic monopole charge induces a repulsive core that halts complete evaporation, resulting in a stable remnant which is significant deviation from traditional singular black hole models. In contrast, the Kiselev–AdS black hole without magnetic charge undergoes total mass loss, illustrating the crucial role of nonlinear electrodynamic effects. Next, we analyze the evolution of scalar perturbations and find that increasing the quintessence parameter enhances wave dissipation, while higher magnetic charge improves perturbative stability through deeper effective potentials. To further understand quantum effects, we compute rigorous bounds on the greybody factors using the Visser–Boonserm method and demonstrate that quintessence suppresses radiation transmission, whereas magnetic charge amplifies it, modifying the observable Hawking spectrum. Additionally, we examine the black hole shadow and find that quintessence shrinks the apparent shadow size, while magnetic charge enlarges it due to modifications in the photon sphere geometry. Lastly, employing the Novikov–Thorne model, we simulate the accretion disk images and show how parameters like q, c, and observer inclination 
impact the disk s shape, and relativistic lensing features.
