  In this work, we study a static, spherically charged AdS black hole within a
modified cosmological Chaplygin gas (MCG), adhering to the calorific equation
of state, as a unified dark fluid model of dark energy and dark matter. We
explore the influence of model parameters on several characteristics of the
MCG-motivated charged AdS black hole (MCGMBH), including the geodesic structure
and some astrophysical phenomena such as null trajectories, shadow silhouettes,
light deflection angles, and the determination of greybody bounds. We then
discuss how the model parameters affect the Hawking temperature, remnant
radius, and evaporation process of the MCGMBH. Quasinormal modes are also
investigated using the eikonal approximation method. Constraints on the MCGMBH
parameters are derived from EHT observations of M87* and Sgr A*, suggesting
that MCGMBH could be strong candidates for astrophysical BH.
