The Weak Lensing Radial Acceleration Relation: Constraining Modified Gravity and Cold Dark Matter theories with KiDS1000
Brouwer et al. (2021), A&A, submitted
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.

KiDS+VIKING450: Cosmic shear tomography with optical+infrared data
Hildebrandt et al. 2019, A&A, submitted (arXiv:1812.06076)
The first combined cosmological measurements of KiDS and VIKING were published in Hildebrandt et al. (2019), based on 450 sq.deg. of KiDS+VIKING data. Based on greatly enhanced 9band photometric redshifts and new image simulations (Kannawadi et al. 2018) this measurement updates the results from Hildebrandt et al. (2017) and significantly increases the systematic robustness.

Euclidera cosmology for everyone: Neural net assisted MCMC sampling for the joint 3x2 likelihood
ManriqueYus & Sellentin (2019), MNRAS, stz3059
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. 2019, arXiv:1910.05336
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.
