Quantifying the global 'CMB tension' between the Atacama Cosmology Telescope and the Planck satellite in extended models of cosmology

Eleonora Di Valentino et al.

Summary: In this study, the global agreement between observations of the cosmic microwave background (CMB) from the Atacama Cosmology Telescope and the Planck satellite is examined in different cosmological models with additional parameters. The Suspiciousness statistic is used to quantify the tension between the two experiments. Results show that the tension is reduced to 1.8 sigma when the effective number of relativistic particles is lower than the standard value, and ranges between 2.3 sigma and 3.5 sigma in other extended models.

Restoring cosmological concordance with early dark energy and massive neutrinos?

Alexander Reeves et al.

Summary: The study investigates whether freeing the total neutrino mass can improve the fit of the early dark energy (EDE) model to galaxy clustering data. Bayesian and frequentist profile likelihood analyses using Planck CMB and BOSS galaxy clustering data show that freeing the total neutrino mass does not significantly improve the fit to galaxy clustering. The worsening fit is mainly caused by background modifications to the late-time expansion rate due to massive neutrinos which affect the measurements of the BAO scale.

Cosmological constraints from H II starburst galaxy, quasar angular size, and other measurements

Shulei Cao et al.

Summary: This study compares the constraints from two compilations of H II starburst galaxy data and tests the model independence of quasar angular size data. The new data compilation provides tighter constraints and prefers lower cosmological parameters values. The quasar data by themselves give relatively model-independent constraints on the characteristic linear size. The joint analysis provides model-independent summary estimates of the Hubble constant, matter density parameter, and characteristic size.

Using lower redshift, non-CMB, data to constrain the Hubble constant and other cosmological parameters

Shulei Cao et al.

Summary: This study uses a combination of cosmological data to constrain cosmological parameters in six different models. The results provide model-independent determinations of the Hubble constant and the current non-relativistic matter density parameter. The error bars in these determinations are larger than those in the flat Lambda CDM model, but mild dark energy dynamics and a little spatial curvature are not ruled out.

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).

What does cosmology tell us about the mass of thermal-relic dark matter?

Summary: The presence of light thermally coupled dark matter has an impact on the early expansion history and production of light elements. By analyzing the temperature and polarization anisotropy of the cosmic microwave background radiation, we provide comprehensive bounds on the mass of light thermal-relic dark matter, considering different models. The combination of different measurements improves the constraints on dark matter mass, and the CMB data has a higher constraining power compared to primordial abundance measurements.

A non-linear solution to the S8 tension?

Alexandra Amon et al.

Summary: Weak galaxy lensing surveys have shown a lower amplitude for the matter fluctuation spectrum than expected, while other measurements such as the expansion history and lensing of the cosmic microwave background anisotropies are consistent with the Planck ?CDM cosmology. In this paper, the authors suggest that the discrepancy can be explained if the matter power spectrum is suppressed more strongly on non-linear scales than previously assumed in weak galaxy lensing analyses. This explanation can be tested using future measurements of the matter fluctuation spectrum on linear scales.

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.

Summary: This study presents angular power spectra and cosmological parameter constraints using the Planck PR4 (NPIPE) maps of the cosmic microwave background. The results show excellent consistency between NPIPE and the Planck 2018 maps at the parameter level, indicating the robustness of the Planck cosmology. The lower noise of NPIPE leads to tighter constraints, providing more precise measurements of the cosmological parameters including beyond-Lambda CDM parameters.

Measuring dark energy with expansion and growth

Louis Perenon et al.

Summary: In this study, we use cosmic chronometer and growth of structure data to derive the redshift evolution of the dark energy equation of state w by employing a novel agnostic approach. We compare the performance of background-based w and growth-based w using Gaussian Processes and find that current data is not precise enough for robust reconstruction of both forms of w. However, with mock data from next-generation surveys, we show that the reconstructions will be reliable and the growth-based w will out-perform the background w. Furthermore, any discrepancy between the two forms of w can serve as a new test for deviations from the standard cosmological model.

Strongly lensed type Ia supernovae as a precise late-Universe probe of measuring the Hubble constant and cosmic curvature

Jing-Zhao Qi et al.

Summary: In this paper, the authors simulate a sample of lensed SNe Ia with time-delay measurements and demonstrate their potential as a powerful cosmological probe. They find that the constraint on the Hubble constant obtained from lensed SNe Ia is better than previous measurements, and can be comparable to the result from Planck 2018 data. The authors also compare lensed quasars and find that they are still useful but less precise as a cosmological probe. The results from both lensed SNe Ia and lensed quasars in the era of LSST are expected to yield valuable information on the Hubble constant and cosmic curvature parameter.

Furthermore, while CMB + BAO + SnIa data provide upper bounds on the coupling strength, low-redshift data strongly support nonvanishing values of the interaction parameters.
