Challenges for ACDM: An update

L. Perivolaropoulos et al.

Summary: In recent years, challenges to the standard ACDM model have been emerging as cosmological observations improve. This review discusses various signals in cosmological and astrophysical data that are in tension with the standard ACDM model, such as the Hubble tension, growth tension, and lensing amplitude anomaly, as well as other less-discussed signals that may hint towards new physics. The goal is to provide an update on the current status of these signals, particularly the Hubble tension, and refer readers to additional resources for more details.

A Comprehensive Measurement of the Local Value of the Hubble Constant with 1 km s-1 Mpc-1 Uncertainty from the Hubble Space Telescope and the SH0ES Team

Adam G. Riess et al.

Summary: This study reports observations of Cepheid variables in the host galaxies of 42 Type Ia supernovae (SNe Ia) using the Hubble Space Telescope (HST) to calibrate the Hubble constant (H (0)). The observations were collected over four decades and significantly improved the precision of the direct determination of H (0). The study presented multiple verifications of Cepheid photometry and explored different analysis variants to assess the sensitivity of H (0) determination. The baseline result for H (0) was found to be 73.04 +/- 1.04 km s(-1) Mpc(-1).

Full-shape galaxy power spectra and the curvature tension

Aaron Glanville et al.

Summary: With recent evidence for a possible 'curvature tension' among early and late universe cosmological probes, Effective Field Theories of Large Scale Structure (EFTofLSS) have emerged as a promising new framework to generate constraints on Ok that are independent of both CMB measurements, and some of the assumptions of flatness that enter into other large-scale structure analyses. In this work we use EFI'olLSS to simultaneously constrain measurements from the 6dFGS, BOSS, and eBOSS catalogues, representing the most expansive full-shape investigation of curvature to date. Using the Bayesian evidence ratio our full-shape data assigns betting odds of 2:1 in favour of curvature, indicating present measurements remain broadly compatible with both flat and curved cosmological models. When our full-shape sample is combined with Planck 2018 CMB measurements, we break the geometric degeneracy and recover a joint fit on Omega(k) of -0.0037(-)(0.0026)(+0.0025) Using the suspiciousness statistic we find evidence for a moderate tension between Planck 2018 and our suite of full-shape measurements, at a significance of 1.86(-0.11)(+0.13)sigma (p similar to 0.06 +/- 0.02). These results demonstrate the usefulness of full-shape clustering measurements as a CMB independent probe of curvature in the ongoing curvature tension debate.

Snowmass2021-Letter of interest cosmology intertwined IV: The age of the universe and its curvature

Eleonora Di Valentino et al.

Summary: A precise measurement of the curvature of the Universe is crucial for cosmology as it can confirm primordial inflation and differentiate between early-Universe scenarios. Recent observations show tensions which may suggest slight deviations from a flat universe, with a preference for a closed universe in some cases. This anomaly could be due to new physics, unresolved systematic errors, or statistical fluctuations, with positive curvature potentially providing evidence for or against the current flat ACDM model.

Summary: The standard A Cold Dark Matter cosmological model fits well with current cosmological data, but significant tensions and anomalies have been found in the latest data analyses. Resolving these tensions may require new physics models and emphasizes the importance of fitting multiple cosmological datasets with complete physical models.

Why reducing the cosmic sound horizon alone can not fully resolve the Hubble tension

Karsten Jedamzik et al.

Summary: The Hubble tension, a discrepancy between the locally measured expansion rate of the universe and that inferred from the cosmic microwave background measurements, has become a pressing issue in cosmology. Various modifications to the ΛCDM model have been proposed to address this tension, but models that only reduce the sound horizon r(*) cannot fully resolve the issue while remaining consistent with other cosmological datasets.

Interacting dark energy in a closed universe

Eleonora Di Valentino et al.

Summary: Recent measurements by the Planck satellite suggest a preference for a closed universe, but this conflicts with low redshift observables such as Type Ia supernovae luminosity distances. Interacting dark energy models could help reconcile these discrepancies in a closed Universe, indicating potential for a different coupling and curvature above 99% confidence level. This highlights the significance of broader cosmological data analyses and the possibility of better agreement between theory and observations by relaxing flatness and vacuum energy assumptions.

Cosmological constraints on Horava gravity revised in light of GW170817 and GRB170817A and the degeneracy with massive neutrinos

Noemi Frusciante et al.

Summary: In this study, we revise the cosmological limits on Horava gravity, while considering the constraints on the speed of propagation of gravitational waves and the relationship between massive neutrinos. The findings suggest that luminal propagation of gravitational waves can suppress large-scale CMB radiation temperature anisotropies, with massive neutrinos increasing this effect. Additionally, it is observed that massive neutrinos can compensate for modifications induced by Horava gravity, but there exists degeneracy with the tensor-to-scalar ratio r in theoretical levels.

Curvature tension: Evidence for a closed universe

Will Handley

Summary: The tension in the curvature parameter measured between Planck 2018, cosmic microwave background (CMB) lensing, and baryon acoustic oscillation (BAO) data is 2.5-3 sigma using the suspiciousness statistic. Conclusions about the spatial curvature of the Universe from these data should be viewed with suspicion. Without CMB lensing or BAO, Planck 2018 has a moderate preference for closed universes.
