Exploring the R\'enyi Holographic Dark Energy Model with the Future and the Particle Horizons as the Infrared Cut-off

TL;DR

This paper investigates the Rényi holographic dark energy model using future and particle horizons as IR cut-offs, finding results consistent with an accelerating universe in a phantom phase.

Contribution

It introduces the Rényi holographic dark energy model with new IR cut-offs and analyzes its cosmological implications using observationally consistent initial conditions.

Findings

Universe is in accelerating expansion

Model predicts a phantom phase

Results align with current cosmological observations

Abstract

We study the R\'enyi holographic dark energy (RHDE) model by using the future and the particle horizons as the infrared (IR) cut-off. With the initial condition from the literature, most of the cosmological parameters are computed. Some of the results agree with the observation that the present universe is in accelerating expansion and in a phantom phase.
