The pith

DESI baryon acoustic oscillation measurements from the first year are consistent with flat LambdaCDM but show a preference for evolving dark energy when combined with CMB or supernova data.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper measures baryon acoustic oscillations using data from the Dark Energy Spectroscopic Instrument's first year, covering galaxy, quasar, and Lyman-alpha forest tracers in seven redshift bins up to z=4.2. These measurements alone support the standard flat LambdaCDM cosmology with a matter density of 0.295 plus or minus 0.015. When combined with cosmic microwave background data from Planck, the constraints tighten to a matter density of 0.307 plus or minus 0.005 and Hubble constant of 67.97 plus or minus 0.38 km/s/Mpc. Extending the model to allow for a time-varying dark energy equation of state, the data show a 2.5 to 3.9 sigma preference for evolving dark energy depending on which supernova dataset is included. The analysis also provides upper limits on the sum of neutrino masses.

Core claim

DESI BAO provide robust measurements of the transverse comoving distance and Hubble rate relative to the sound horizon in seven redshift bins from over 6 million objects, yielding cosmological constraints consistent with flat LambdaCDM for the baseline model while combinations with CMB and supernova data favor models with w0 greater than -1 and wa less than 0 at up to 3.9 sigma significance.

What carries the argument

Baryon acoustic oscillations extracted from galaxy, quasar and Lyman-alpha forest tracers as standard rulers to measure distance-redshift relations relative to the sound horizon.

Load-bearing premise

The BAO scale extraction assumes that standard models of galaxy bias, redshift-space distortions and reconstruction fully account for all relevant systematics without leaving significant residuals.

What would settle it

A reanalysis of the same DESI spectra using substantially different modeling of redshift-space distortions or reconstruction that shifts the reported BAO scales by more than the quoted uncertainties would falsify the cosmological constraints.

read the original abstract

We present cosmological results from the measurement of baryon acoustic oscillations (BAO) in galaxy, quasar and Lyman-$\alpha$ forest tracers from the first year of observations from the Dark Energy Spectroscopic Instrument (DESI), to be released in the DESI Data Release 1. DESI BAO provide robust measurements of the transverse comoving distance and Hubble rate, or their combination, relative to the sound horizon, in seven redshift bins from over 6 million extragalactic objects in the redshift range $0.1<z<4.2$. DESI BAO data alone are consistent with the standard flat $\Lambda$CDM cosmological model with a matter density $\Omega_\mathrm{m}=0.295\pm 0.015$. Paired with a BBN prior and the robustly measured acoustic angular scale from the CMB, DESI requires $H_0=(68.52\pm0.62)$ km/s/Mpc. In conjunction with CMB anisotropies from Planck and CMB lensing data from Planck and ACT, we find $\Omega_\mathrm{m}=0.307\pm 0.005$ and $H_0=(67.97\pm0.38)$ km/s/Mpc. Extending the baseline model with a constant dark energy equation of state parameter $w$, DESI BAO alone require $w=-0.99^{+0.15}_{-0.13}$. In models with a time-varying dark energy equation of state parametrized by $w_0$ and $w_a$, combinations of DESI with CMB or with SN~Ia individually prefer $w_0>-1$ and $w_a<0$. This preference is 2.6$\sigma$ for the DESI+CMB combination, and persists or grows when SN~Ia are added in, giving results discrepant with the $\Lambda$CDM model at the $2.5\sigma$, $3.5\sigma$ or $3.9\sigma$ levels for the addition of Pantheon+, Union3, or DES-SN5YR datasets respectively. For the flat $\Lambda$CDM model with the sum of neutrino mass $\sum m_\nu$ free, combining the DESI and CMB data yields an upper limit $\sum m_\nu < 0.072$ $(0.113)$ eV at 95% confidence for a $\sum m_\nu>0$ $(\sum m_\nu>0.059)$ eV prior. These neutrino-mass constraints are substantially relaxed in models beyond $\Lambda$CDM. [Abridged.]

Referee Report

1 major / 2 minor

Summary. The manuscript reports cosmological constraints from baryon acoustic oscillation (BAO) measurements extracted from the first year of DESI observations (Data Release 1), using galaxy, quasar, and Lyman-alpha forest tracers across seven redshift bins spanning 0.1 < z < 4.2. DESI BAO data alone are consistent with flat LambdaCDM (Omega_m = 0.295 +/- 0.015); combined with BBN and Planck CMB data they yield Omega_m = 0.307 +/- 0.005 and H0 = 67.97 +/- 0.38 km/s/Mpc. Extensions to constant-w and w0-wa dark energy models show consistency with w = -1 from BAO alone but 2.5-3.9 sigma preferences for evolving dark energy (w0 > -1, wa < 0) when supernova datasets are added; neutrino mass limits are also derived.

Significance. If the BAO scale measurements hold, this work delivers the first major cosmological results from DESI, adding seven new high-precision distance and expansion-rate anchors that tighten constraints on Omega_m, H0, and dark energy evolution. The reported consistency with LambdaCDM from BAO alone, the H0 value from BBN+CMB+DESI, and the quantified tension levels in w0-wa extensions when SN data are included provide falsifiable tests that can be checked with future data releases. The neutrino-mass upper limits are competitive within the stated priors.

major comments (1)
  1. [BAO measurement and fitting pipeline (sections describing template fits to galaxy, quasar, and Lyman-alpha tracers)] The central claims (flat LambdaCDM consistency, H0 value, and w0-wa tension levels) rest directly on the seven extracted BAO scales (D_M/r_d and D_H/r_d or their combination). The extraction pipeline uses standard linear bias, RSD modeling, and reconstruction; any unaccounted residual scale-dependent bias or reconstruction artifact would shift these scales and propagate into the posteriors. A dedicated section quantifying the impact of these assumptions (e.g., via mock-based residual tests or alternative modeling) is needed to confirm that the reported 2.5-3.9 sigma deviations are not driven by modeling choices.
minor comments (2)
  1. [Abstract and Section 2] The abstract and main text should explicitly state the total number of objects and the precise redshift bin boundaries for each tracer to allow immediate reproducibility checks.
  2. [Results and data tables] Covariance matrices between the seven BAO measurements and their combination with external datasets should be provided in a machine-readable format or clearly tabulated to support independent re-analyses.

  1. Referee: [BAO measurement and fitting pipeline (sections describing template fits to galaxy, quasar, and Lyman-alpha tracers)] The central claims (flat LambdaCDM consistency, H0 value, and w0-wa tension levels) rest directly on the seven extracted BAO scales (D_M/r_d and D_H/r_d or their combination). The extraction pipeline uses standard linear bias, RSD modeling, and reconstruction; any unaccounted residual scale-dependent bias or reconstruction artifact would shift these scales and propagate into the posteriors. A dedicated section quantifying the impact of these assumptions (e.g., via mock-based residual tests or alternative modeling) is needed to confirm that the reported 2.5-3.9 sigma deviations are not driven by modeling choices.

    Authors: We agree that explicit quantification of modeling assumptions in the BAO extraction is important for supporting the central claims. The seven BAO scales are derived from template fits whose details and validation are presented in the companion measurement papers (DESI 2024 I-V). Those works include extensive mock-based tests for residual scale-dependent bias, reconstruction artifacts, and alternative RSD/bias modeling choices, showing that any such effects remain well below the statistical precision of the measurements. To directly address the referee's request, we have added a new dedicated subsection (Section 3.4 in the revised manuscript) that summarizes these validation results, reports the quantified residual biases on D_M/r_d and D_H/r_d, and confirms that they do not shift the extracted scales at a level capable of driving the reported 2.5-3.9 sigma preferences in the w0-wa extensions. We also briefly discuss consistency checks with alternative fitting pipelines. This addition ensures the robustness discussion is self-contained within the present paper. revision: yes

Circularity Check

DESI BAO cosmological constraints derived from new data fits with no reduction by construction

full rationale

The paper reports new BAO scale measurements (D_M/r_d, D_H/r_d) extracted from DESI galaxy, quasar and Lyman-alpha data in seven redshift bins, then fits these scales to cosmological models (flat LambdaCDM, wCDM, w0waCDM) using standard likelihoods plus independent external priors (BBN, Planck CMB). No equation or step equates a reported constraint to a quantity defined by the same fit; the measured scales are independent observables, and methodology citations to prior DESI papers describe standard bias/RSD/reconstruction templates that are externally falsifiable. This yields a minor self-citation score without load-bearing circularity.

    astro-ph.CO 2026-04 unverdicted novelty 6.0

    A new quintessence model with non-minimal coupling produces an effective sign-switching interaction that fits current data better than LambdaCDM or w0waCDM and accounts for late-time dark energy weakening without phan...

  47. A Spectrum of Cosmological Rips and Their Observational Signatures

    astro-ph.CO 2025-12 conditional novelty 6.0

    A unified dark energy model with sigmoid correction generates a spectrum of rip futures that all fit DESI, Pantheon+, and CMB data at the same level as ΛCDM.

  48. $H_0$ Without the Sound Horizon (or Supernovae): A 2% Measurement in DESI DR1

    astro-ph.CO 2025-10 conditional novelty 6.0

    A heuristic power-spectrum rescaling applied to DESI DR1 BAO data plus CMB acoustic scale anchor yields H0 values of 69.2 to 70.3 km/s/Mpc at sub-2% precision across three independent late-time datasets.

  49. Nonlinear Matter Power Spectrum from relativistic $N$-body Simulations: $\Lambda_{\rm s}$CDM versus $\Lambda$CDM

    astro-ph.CO 2025-10 unverdicted novelty 6.0

    Relativistic N-body simulations of Lambda_s CDM produce a redshift-dependent crest in the matter power spectrum ratio, peaking at 20-25% near the transition and leaving a 15-20% uplift at z=0 on group scales.

  50. Dynamic or Systematic? Bayesian model selection between dark energy and supernova biases

    astro-ph.CO 2025-09 unverdicted novelty 6.0

    A magnitude offset between low- and high-redshift supernovae beats the Bayesian evidence for flexknot dark energy and reduces DES-5Y/DESI tension.

  51. DESI Dark Secrets

    astro-ph.CO 2025-02 conditional novelty 6.0

    DESI data prefer w0wa models over LambdaCDM but scalar-field models with β fit worse individually; combined with Planck CMB and Pantheon+ SNe the data favor 0.27 < β < 1.03 at 95% credibility.

  52. DESI 2024 VII: Cosmological Constraints from the Full-Shape Modeling of Clustering Measurements

    astro-ph.CO 2024-11 accept novelty 6.0

    DESI DR1 full-shape clustering yields Ω_m = 0.2962 ± 0.0095 and σ_8 = 0.842 ± 0.034 in flat ΛCDM, tightening to H_0 = 68.40 ± 0.27 km/s/Mpc with CMB and DESY3, while favoring w_0 > -1, w_a < 0 and limiting neutrino ma...

  53. DESI 2024 V: Full-Shape Galaxy Clustering from Galaxies and Quasars

    astro-ph.CO 2024-11 accept novelty 6.0

    DESI DR1 full-shape galaxy clustering constrains Omega_m = 0.296 ± 0.010, H0 = 68.63 ± 0.79 km/s/Mpc, and sigma_8 = 0.841 ± 0.034, consistent with LambdaCDM and Planck.

  54. Assessing observational constraints on dark energy

    astro-ph.CO 2024-05 conditional novelty 6.0

    Quintessence models satisfying NEC everywhere predict the w0 > -1 and w0+wa < -1 sector favored by data, due to an approximate degeneracy in the w(z) = w0 + wa z/(1+z) parameterization.

  55. DESI 2024 IV: Baryon Acoustic Oscillations from the Lyman Alpha Forest

    astro-ph.CO 2024-04 accept novelty 6.0

    DESI measures BAO from the Lyα forest at z_eff=2.33, reporting H(z) = (239.2 ± 4.8) (147.09 Mpc/rd) km/s/Mpc and DM(z) = (5.84 ± 0.14) (rd/147.09 Mpc) Gpc.

  56. A hidden reionization prior biases cosmological inference

    astro-ph.CO 2026-06 unverdicted novelty 5.0

    No monotonic reionization history fits Planck τ, patchy kSZ from SPT/ACT, and Lyα endpoint; an early ionization phase at z≳12 relaxes ∑mν<0.39 eV and shifts σ8 via As-τ degeneracy.

  59. Late-Time Oscillating Quintessence in Light of DESI

    astro-ph.CO 2026-06 unverdicted novelty 5.0

    A late-onset oscillating quintessence model improves the fit to DESI plus supernova and CMB data by Delta chi squared of about 9 over Lambda CDM, driven by background expansion.

  60. Microscopic entropy of de Sitter spacetime and entropic solution to the old cosmological constant problem

    hep-th 2026-06 unverdicted novelty 5.0
