📌 Abstract : A challenge remains to be overcome in the dark energy model that describes the accelerated expansion of the Universe during the late-time epoch. In this talk, we are focused on holographic dark energy (HDE). For such dark energy, its energy density is defined as matter with saturated energy that does not collapse into a black hole. Based on the Rényi description of black hole thermodynamics, the phase space of the black hole must be reconsidered. As a result, the form of the energy density gets modified. It is found that this model can recover the standard LambdaCDM model and also contains a significant feature in driving the Universe to expand with acceleration. From observational data, a comparison between this HDE model and other related models is presented.
