    Newest Measurements of Hubble Constant from DESI 2024 Baryon Acoustic Oscillation Observations by Wuzheng Guo, Qiumin Wang, Shuo Cao, Marek Biesiada, Tonghua Liu, Yujie Lian, Xinyue Jiang, Chengsheng Mu, Dadian Cheng

    Published 2025-01-01
    “…In this Letter, we use the latest results from the Dark Energy Spectroscopic Instrument (DESI) survey to measure the Hubble constant. Baryon acoustic oscillation (BAO) observations released by the DESI survey, allow us to determine H _0 from the first principles. …”

    5σ tension between Planck cosmic microwave background and eBOSS Lyman-alpha forest and constraints on physics beyond ΛCDM by Keir K. Rogers, Vivian Poulin

    Published 2025-01-01
    “…We find that combined Planck cosmic microwave background, baryon acoustic oscillations, and supernovae data analyzed under Λ cold dark matter (ΛCDM) are in 4.9σ tension with the extended Baryon Oscillation Spectroscopic Survey (eBOSS) Lyα forest in inference of the linear matter power spectrum at wave number ∼1hMpc^{−1} and redshift = 3. …”

    Reconstruction of the scalar field potential in nonmetricity gravity through Gaussian processes by Gaurav N. Gadbail, Sanjay Mandal, P.K. Sahoo, Kazuharu Bamba

    Published 2025-01-01
    “…Employing the Gaussian process method with a square exponential kernel, we reconstruct the scalar field potential, V(ϕ), from observational Hubble data sets coming from cosmic chronometers (CC) as well as from the method of radial baryon acoustic oscillations (BAO) in a model-independent approach. …”

    A comparison of Bayesian and frequentist confidence intervals in the presence of a late Universe degeneracy by Eoin Ó. Colgáin, Saeed Pourojaghi, M. M. Sheikh-Jabbari, Darragh Sherwin

    Published 2025-02-01
    “…Finally, on the assumption that the Planck- $$\Lambda $$ Λ CDM cosmological model is correct, using profile likelihoods we confirm a $$>2 \sigma $$ > 2 σ discrepancy with Planck- $$\Lambda $$ Λ CDM in a combination of CC and baryon acoustic oscillations (BAO) data beyond $$z \sim 1.5$$ z ∼ 1.5 . …”

    On the Evidence of Dynamical Dark Energy by Qing Gao, Zhiqian Peng, Shengqing Gao, Yungui Gong

    Published 2024-12-01
    “…To elucidate the robustness of the baryon acoustic oscillation (BAO) data measured by the dark energy spectroscopic instrument (DESI) in capturing the dynamical behavior of dark energy, we assess the model dependence of the evidence for dynamical dark energy inferred from the DESI BAO data. …”
