Cosmological analyses

KiDS+VIKING-450: Cosmic shear tomography with optical+infrared data

Hildebrandt et al. 2018, A&A, submitted (arXiv:1812.06076)

The first combined cosmological measurements of KiDS and VIKING were published in Hildebrandt et al. (2018), based on 450 sq.deg. of KiDS+VIKING data. Based on greatly enhanced 9-band 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.

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 two-point weak lensing shear correlation functions measured from KiDS-450 data (see Hildebrandt et al. 2017 below). Applying these consistency tests then to the KiDS-450 data, we do not find any evidence for significant internal tension, with significances below 3 σ in all cases.

KiDS+GAMA: Cosmology constraints from a joint analysis of cosmic shear, galaxy-galaxy lensing and angular clustering

van Uitert et al. 2018, MNRAS, 476, 4662

Based on 450 square degrees of survey data, this is a joint cosmological analysis of cosmic shear, galaxy-galaxy lensing, and angular galaxy clustering. All probes are measured in terms of tomographic band powers integrated over correlation functions. A number of scientific data products are available, including MCMC chains, data vectors, the covariance matrix, and redshift distributions.All data files are accompanied by detailed README files.

KiDS-450: weak lensing power spectrum

Köhlinger et al. 2017, MNRAS, 471, 4412

Based on 450 square degrees of survey data, an analysis of the weak gravitational lensing shear power spectrum was published in KiDS-450: the tomographic weak lensing power spectrum and constraints on cosmological parameters (Köhlinger et al. 2017, MNRAS, 471, 4412). A number of scientific data products are available, including MCMC chains, data vectors, the covariance matrix, and redshift distributions, as well as software code specifically written for the analysis. More details can be found in the paper (linked below) and all data files are accompanied by detailed README files.

KiDS-450: Cosmological parameter constraints

Hildebrandt & Viola et al. 2017, MNRAS, 465, 1454

Based on 450 square degrees of survey data, the first cosmological parameter constraints from KiDS were published in KiDS-450: Cosmological parameter constraints from tomographic weak gravitational lensing (Hildebrandt & Viola et al. 2017, MNRAS, 465, 1454).

Catalogs

KiDS+VIKING-450 catalog

The KiDS+VIKING-450 weak lensing shear catalog formed the basis of the first tomographic weak lensing analysis based on a combination of KiDS and VIKING data. Based on the same data set as KiDS DR3, spanning 450 square degrees, although the released shear catalog is filtered to include only sources with reliable shear measurements. Details regarding the catalog can be found on the dedicated webpage linked below.
