Dark Energy Survey Year 3 Results: clustering redshifts - calibration of the weak lensing source redshift distributions with redMaGiC and BOSS/eBOSS

M. Gatti et al.

Summary: In this study, we calibrated the redshift distribution n(z) of DES Y3 weak lensing source galaxies using clustering measurements. Two methods were used, and their uncertainties were evaluated through simulations. The results showed that both methods accurately estimated the redshift distribution of the source galaxies.

Galaxy And Mass Assembly (GAMA): Data Release 4 and the z < 0.1 total and z < 0.08 morphological galaxy stellar mass functions

Simon P. Driver et al.

Summary: In the Galaxy And Mass Assembly Data Release 4 (GAMA DR4), a full spectroscopic redshift sample is provided, which includes 248,682 galaxy spectra and a total of 330,542 redshifts. This data set has the highest redshift density and high completeness, making it suitable for studying galaxy mergers, galaxy groups, and low redshift galaxy population. The release also includes additional measured and derived data products. The analysis of the data reveals the total galaxy stellar mass function and its subdivision by morphological class.

Dark Energy Survey Year 3 results: Cosmology from cosmic shear and robustness to data calibration

A. Amon et al.

Summary: This work presents the Dark Energy Survey Year 3 cosmic-shear measurements and cosmological constraints based on an analysis of over 100 million source galaxies, while a companion paper provides further details. The measurements are consistent with the Λ CDM model and yield precise results for the clustering amplitude and S-8. The low-redshift measurements agree with the Planck Cosmic Microwave Background result, but the high-redshift prediction is lower. The measurements demonstrate internal consistency and robustness to calibration systematics and blending of galaxies. The precision of the cosmological constraints is mainly limited by modeling baryonic effects and intrinsic alignments.

Dark Energy Survey Year 3 results: Cosmology from cosmic shear and robustness to modeling uncertainty

L. F. Secco et al.

Summary: This paper presents cosmic shear measurements and cosmological constraints from the Darki Energy Survey (DES) Year 3 data, using over 100 million source galaxies. The lensing amplitude parameter S-8 is constrained at the 3% level in the ΛCDM model, and the robustness of the results to modeling of intrinsic alignments is explored. Constraints from other weak lensing experiments and the Cosmic Microwave Background (CMB) are compared, and the statistical preference for different complexity intrinsic alignment models is examined.

KiDS-1000 cosmology: Cosmic shear constraints and comparison between two point statistics

Marika Asgari et al.

Summary: The study presents cosmological constraints using the fourth data release of the Kilo-Degree Survey (KiDS-1000), revealing tension with the Planck Legacy analysis predictions. The results from the fiducial COSEBIs analysis align well with other complementary analyses, indicating robust S-8 constraints dominated by statistical errors.

KiDS-1000 methodology: Modelling and inference for joint weak gravitational lensing and spectroscopic galaxy clustering analysis

B. Joachimi et al.

Summary: This paper presents a methodology for joint cosmological analysis using weak gravitational lensing and galaxy clustering data from multiple surveys. The analysis incorporates cross-correlations, develops a hybrid model for non-linear scales, updates calibration procedures, and assesses signal contributions from astrophysical effects. The study also validates likelihood and goodness-of-fit statistics, introduces a new prior on the structure growth parameter, and proposes an alternative estimator for S-8 weak lensing constraints. Systematic effects are shown to bias S-8 by no more than 0.1 standard deviations, with expected improvements in S-8 constraints compared to previous analyses.

KiDS-1000 Cosmology: Multi-probe weak gravitational lensing and spectroscopic galaxy clustering constraints

Catherine Heymans et al.

Summary: This study combines weak gravitational lensing observations from KiDS-1000, redshift-space galaxy clustering observations from BOSS, and galaxy-galaxy lensing observations from overlapping surveys to constrain the structure growth parameter S-8, resulting in a discrepancy with the Planck observations by 8.3% relative to Planck. The systematic uncertainties identified through various analyses are incorporated into the cosmological analysis, revealing a tension in the matter fluctuation amplitude parameter, sigma(8).

KiDS-1000 catalogue: Weak gravitational lensing shear measurements

Benjamin Giblin et al.

Summary: This study presents weak lensing shear catalogues from the KiDS-1000 survey, evaluating the accuracy of the PSF model and validating the shear estimates. No significant non-lensing B-mode distortions were found in the data, with low amplitude of PSF residuals detected in the highest-redshift bins. The joint KiDS-1000 shear and photometric redshift calibration is deemed sufficiently robust for combined-probe gravitational lensing and spectroscopic clustering analyses.

The PAU Survey: an improved photo-z sample in the COSMOS field

Alex Alarcon et al.

Summary: We have presented and made publicly available accurate and precise photometric redshifts for objects with i(AB) <= 23 in the ACS footprint from the COSMOS field. By combining narrow-band photometry from PAUS and 26 bands from the COSMOS2015 catalogue, a new method was introduced to model spectral energy distributions and compute redshifts. The photometric redshifts were found to be more precise and very accurate compared to previous estimates, showcasing the impact of the added PAUS data and new methodology.
