    Sep 13, 2024We use an empirical galaxy formation model to explore the potential of alleviating these tensions through an Early Dark Energy (EDE) model, originally proposed to solve the Hubble tension. Our benchmark model demonstrates excellent agreement with the UV luminosity functions (UVLFs) at |$4\lesssim z \lesssim 10$| in both ΛCDM and EDE cosmologies.

    Nov 23, 2024The Holographic Principle, as discussed by Li [1] and Nojiri et al. [2], is a significant theoretical framework for understanding the evolution of the universe.Applying the concept of holographic dark energy can provide insights into quantum gravity. This principle has been applied to both the early and late stages of the universe as evidenced by the work of Nojiri and Odintsov [3], [4] and ...
  4. One possible mechanism for achieving this increased expansion at early times is "Early Dark Energy" (EDE), where a new cosmological energy source with an equation of state similar to dark energy contributes ∼ 10 % similar-to absent percent 10 \sim 10\% ∼ 10 % of the critical density at its time of maximal contribution (z ∼ 3000 ...

    Aug 1, 2023We show that Early Dark Energy can be described by such model and also a phantom transition is achieved. The paper is organized as follows: In Section 2 EGB gravity is introduced. Section 3 is devoted to the reconstruction procedure for obtaining a unified model. Inflation is analyzed in Section 4 while Phantom dark energy is studied in Section 5.

    Early dark energy (EDE) that behaves like a cosmological constant at early times (redshifts ) and then dilutes away like radiation or faster at later times can solve the Hubble tension.In these models, the sound horizon at decoupling is reduced resulting in a larger value of the Hubble parameter inferred from the cosmic microwave background (CMB). ). We consider two physical models for this ...

    Aug 7, 2023Early dark energy (EDE) offers a solution to the so-called Hubble tension. Recently, it was shown that the constraints on EDE using Markov Chain Monte Carlo are affected by prior volume effects. The goal of this paper is to present constraints on the fraction of EDE, f EDE, and the Hubble parameter, H0, which are not subject to prior volume ...

    Jan 10, 2024To address this tension, early dark energy (EDE) models have been proposed as alternatives to Lambda cold dark matter, as they can change the observed sound horizon and the inferred Hubble constant from measurements based on this. In this paper, we investigate the use of Bayesian model averaging (BMA) to evaluate EDE as a solution to the H 0 ...
