Constraints on the interacting holographic dark energy model

TL;DR

This paper constrains the interacting holographic dark energy model considering spatial curvature, showing it can explain a transition in dark energy's equation of state from above to below -1, consistent with accelerated expansion.

Contribution

It provides new parameter constraints for the interacting holographic dark energy model in a curved universe, highlighting its ability to describe dark energy transition.

Findings

Model accommodates transition of dark energy from >-1 to <-1.

Constraints support accelerated expansion in curved universe.

Model remains consistent with near-flatness condition.

Abstract

We examined the interacting holographic dark energy model in a universe with spatial curvature. Using the near-flatness condition and requiring that the universe is experiencing an accelerated expansion, we have constrained the parameter space of the model and found that the model can accommodate a transition of the dark energy from $\omega_D>-1$ to $\omega_D<-1$.
