abstract

A model for holographic dark energy is proposed, following the idea that the short distance cut-off is related to the infrared cut-off. We assume that the infrared cut-off relevant to the dark energy is the size of the event horizon. With the input $\Omega_\Lambda=0.73$, we predict the equation of state of the dark energy at the present time be characterized by $w=-0.90$. The cosmic coincidence problem can be resolved by inflation in our scenario, provided we assume the minimal number of e-folds.

  3. Measuring neutrino mass in light of ACT DR6 and DESI DR2

    astro-ph.CO 2026-03 unverdicted novelty 5.0 of 10

    New ACT and DESI data yield model-dependent upper limits on sum of neutrino masses, with holographic dark energy giving the tightest bounds and a consistent preference for degenerate hierarchy.

  4. Hubble Tension as an Effect of Horizon Entanglement Nonequilibrium

    astro-ph.CO 2026-01 reject novelty 5.0 of 10

    A phenomenological 'horizon entanglement deficit' with the form ρ ∝ H² is fit to low-z data under a forced H0=73 prior; the nonzero amplitude is a restatement of that prior.

  5. Hints Beyond $\Lambda$CDM from Barrow and Tsallis Holographic Dark Energy with GO cutoff

    gr-qc 2026-01 conditional novelty 5.0 of 10

    Barrow holographic dark energy with the Granda-Oliveros cutoff fits current background data as well as ΛCDM and shows a weak AIC preference only for the Union3-based dataset combination.

  6. Reconstructing $f(R)$ gravity from Viaggiu Holographic Dark Energy under Hubble, Event Horizon and Granda Oliveros cutoffs

    gr-qc 2026-07 conditional novelty 4.0 of 10

    Explicit f(R) forms obtained by equating VHDE density to curvature density under Hubble, event-horizon and Granda-Oliveros cutoffs describe late-time acceleration and satisfy standard viability conditions.

  7. Late-time cosmological constraints on three holographic dark energy models with DESI DR2 BAO and Type Ia supernovae

    physics.gen-ph 2026-07 accept novelty 4.0 of 10

    DESI DR2 and late-time data constrain HDE, ADE and RDE, yielding H0≈67–68 km/s/Mpc, c≈1, n≈2.8, γ≈0.54, with none resolving the Hubble tension or decisively beating ΛCDM.

  8. The open-Universe signal: A model artifact rather than genuine curvature

    astro-ph.CO 2026-04 unverdicted novelty 4.0 of 10

    The mild open-universe signal in late-Universe data is an artifact of assuming the basic ΛCDM model rather than evidence for genuine spatial curvature.

  9. Barrow holographic dark energy interacting model in the presence of radiation and matter

    gr-qc 2026-07 conditional novelty 3.5 of 10

    Interacting ghost dark energy in Kaniadakis-corrected cosmology mildly shifts acceleration onset and approaches ΛCDM, remaining generally unstable though less so for larger λ.

    MCMC constraints on two Lambda(t) models with DESI DR2, CC, and Pantheon+ data yield H0 ~72.5-73 km/s/Mpc, Omega_m0 near standard values in joint fits, and n~0.3 indicating mild deviation from LambdaCDM.
