Cosmological analyses
DES Y3 + KiDS1000: Consistent Cosmology combining cosmic shear surveys
Dark Energy Survey and KiloDegree Survey Collaboration, 2023, OJA
We present a joint cosmic shear analysis of the Dark Energy Survey (DES Y3) and the KiloDegree Survey (KiDS1000) in a collaborative effort between the two survey teams. We find consistent cosmological parameter constraints between DES Y3 and KiDS1000 which, when combined in a jointsurvey analysis, constrain the parameter S_{8} = σ_{8} √(Ω_{m}/0.3) with a mean value of 0.790^{+0.018}_{0.014}. The mean marginal is lower than the maximum a posteriori estimate, S_{8}=0.801, owing to skewness in the marginal distribution and projection effects in the multidimensional parameter space. Our results are consistent with S_{8} constraints from observations of the cosmic microwave background by Planck, with agreement at the 1.7σ level. We use a Hybrid analysis pipeline, defined from a mock survey study quantifying the impact of the different analysis choices originally adopted by each survey team. We review intrinsic alignment models, baryon feedback mitigation strategies, priors, samplers and models of the nonlinear matter power spectrum.
This data release contains the cosmological parameter posteriors from the Hybrid reanalysis of DES Y3 and KiDS1000 cosmic shear, and the joint analysis of the two surveys.

KiDS1000: Cosmic shear with enhanced redshift calibration
van den Busch et al., 2022, A&A 664, A170
We present a cosmic shear analysis with an improved redshift calibration for the fourth data release of the KiloDegree Survey (KiDS1000) using selforganising maps (SOMs). Compared to the previous analysis of the KiDS1000 data, we expand the redshift calibration sample to more than twice its size, now consisting of data of 17 spectroscopic redshift campaigns, and significantly extending the fraction of KiDS galaxies we are able to calibrate with our SOM redshift methodology. We then enhanced the calibration sample with precision photometric redshifts from COSMOS2015 and the Physics of the Accelerated Universe Survey (PAUS), allowing us to fill gaps in the spectroscopic coverage of the KiDS data. Finally we performed a Complete Orthogonal Sets of E/BIntegrals (COSEBIs) cosmic shear analysis of the newly calibrated KiDS sample to show the robustness of the cosmological constraints with respect to the choice of redshift calibration data.
This data release contains the redshift distributions, COSEBI data vectors and covariance matrix, and MCMC chains for the gold samples, see the README.md file included in the tarball.

The Weak Lensing Radial Acceleration Relation: Constraining Modified Gravity and Cold Dark Matter theories with KiDS1000
Brouwer et al., 2021, A&A, 650, A113
We present measurements of the radial gravitational acceleration around isolated galaxies, comparing the expected gravitational acceleration given the baryonic matter in the system (g_bar) with the observed gravitational acceleration (g_obs), using weak lensing measurements from the fourth data release of the KiloDegree Survey (KiDS1000). These measurements extend the radial acceleration relation (RAR), traditionally measured using galaxy rotation curves, by 2 decades in g_obs into the low acceleration regime beyond the outskirts of the observable galaxy.
In this data release, each text file contains one Excess Surface Density (ESD) profile obtained using weak gravitational lensing with KiDS1000. These ESD profiles correspond to the lensing Radial Acceleration Relation (RAR) results shown in the respective figures of Brouwer et al. (2021) as explained in the README file.

Euclidera cosmology for everyone: Neural net assisted MCMC sampling for the joint 3x2 likelihood
ManriqueYus & Sellentin, 2020, MNRAS, 491, 2655
We develop a fully noninvasive use of machine learning in order to enable open research on Euclidsized data sets. Our algorithm leaves complete control over theory and data analysis, unlike many blackbox like uses of machine learning. Focusing on a `3x2 analysis' which combines cosmic shear, galaxy clustering and tangential shear at a Euclidlike sky coverage, we arrange a total of 348000 data points into data matrices whose structure permits not only an easy prediction by neural nets, but it additionally permits the essential removal from the data of patterns which the neural nets could not `understand'. The latter provides an often lacking mechanism to control and debias the inference of physics. The theoretical backbone to our neural net training can be any conventional (deterministic) theory code, where we chose CLASS. After training, we infer the seven parameters of a wCDM cosmology by Monte Carlo Markov sampling posteriors at Euclidlike precision within a day. We publicly provide the neural nets which memorise and output all 3x2 power spectra at a Euclidlike sky coverage and redshift binning.

KiDS+VIKING450 and DESY1 combined: Mitigating baryon feedback uncertainty with COSEBIs
Asgari et al. 2020, A&A 634, 127
Cosmological constraints from a joint cosmic shear analysis of the KiloDegree Survey (KV450) and the Dark Energy Survey (DESY1), using Complete Orthogonal Sets of E/BIntegrals (COSEBIs). With COSEBIs we isolate any Bmodes which have a noncosmic shear origin and demonstrate the robustness of our cosmological Emode analysis as no significant Bmodes are detected. We highlight how COSEBIs are fairly insensitive to the amplitude of the nonlinear matter power spectrum at high kscales, mitigating the uncertain impact of baryon feedback in our analysis. COSEBIs, therefore, allow us to utilise additional smallscale information, improving the DESY1 joint constraints on S8=σ8(Ωm/0.3)0.5 and Ωm by 20%. Adopting a flat ΛCDM model we find S8=0.755+0.019−0.021, which is in 3.2σ tension with the Planck Legacy analysis of the cosmic microwave background.

A Bayesian quantification of consistency in correlated datasets
Köhlinger et al. 2019, MNRAS, 484, 3126
We present a novel suite of Bayesian consistency tests for correlated datasets. Without loss of generality we focus on mutually exclusive, correlated subsets of the same dataset in this work. An example for such a dataset are the twopoint weak lensing shear correlation functions measured from KiDS450 data (see Hildebrandt et al. 2017 below). Applying these consistency tests then to the KiDS450 data, we do not find any evidence for significant internal tension, with significances below 3 σ in all cases.
