Contribution

It provides a refined analysis of the holographic dark energy model including spatial curvature effects and compares predictions with observational data.

Findings

Closed universe is favored by supernova data.

Refined model parameters align with WMAP data.

Holographic dark energy does not behave as phantom energy.

Abstract

We have reexamined the holographic dark energy model by considering the spatial curvature. We have refined the model parameter and observed that the holographic dark energy model does not behave as phantom model. Comparing the holographic dark energy model to the supernova observation alone, we found that the closed universe is favored. Combining with the Wilkinson Microwave Anisotropy Probe (WMAP) data, we obtained the reasonable value of the spatial curvature of our universe.
