Abstract
Holographic dark energy(HDE) models, based on the holographic principle, offer a quantum gravity-inspired explanation for the universe's late-time acceleration. In HDE models, the vacuum energy density relates to an infrared (IR) cutoff, determined by horizon scales. In this study, we performed parameter estimation using the latest observational data, including Type Ia Supernovae, GRBs, and observed Hubble parameters across various holographic dark energy models. We employ the Markov Chain Monte Carlo (MCMC) method to evaluate the viability of these models. Our results show that holographic dark energy models are consistent with existing data and provide insights into the dynamic nature of dark energy. This research highlights the deep connection between cosmological observations and quantum gravity concepts to enhance our understanding of cosmic acceleration.
