Tightening weak lensing constraints on the ellipticity of galaxy-scale dark matter haloes
Tim Schrabback, Henk Hoekstra, Ludovic Van Waerbeke +19
Cosmological simulations predict that galaxies are embedded into triaxial dark matter haloes, which appear approximately elliptical in projection. Weak gravitational lensing allows…
KiDS-1000 Cosmology: constraints beyond flat CDM
Tilman Tröster, Marika Asgari, Chris Blake +26
We present constraints on extensions to the flat CDM cosmological model by varying the spatial curvature , the sum of the neutrino masses , the dark energy equati…
Photometric selection and redshifts for quasars in the Kilo-Degree Survey Data Release 4
S. J. Nakoneczny, M. Bilicki, A. Pollo +10
We present a catalog of quasars and corresponding redshifts in the Kilo-Degree Survey (KiDS) Data Release 4. We trained machine learning (ML) models, using optical ugri and near-in…
Accounting for object detection bias in weak gravitational lensing studies
Henk Hoekstra, Arun Kannawadi, Thomas D. Kitching
Weak lensing by large-scale structure is a powerful probe of cosmology if the apparent alignments in the shapes of distant galaxies can be accurately measured. Most studies have th…
Mitigating the effects of undersampling in weak lensing shear estimation with metacalibration
Arun Kannawadi, Erik Rosenberg, Henk Hoekstra
Metacalibration is a state-of-the-art technique for measuring weak gravitational lensing shear from well-sampled galaxy images. We investigate the accuracy of shear measured with m…
KiDS+VIKING-450: An internal-consistency test for cosmic shear tomography with a colour-based split of source galaxies
Shun-Sheng Li, Konrad Kuijken, Henk Hoekstra +3
We performed an internal-consistency test of the KiDS+VIKING-450 (KV450) cosmic shear analysis with a colour-based split of source galaxies. Utilising the same measurements and cal…
Clustering of red-sequence galaxies in the fourth data release ofthe Kilo-Degree Survey
Mohammadjavad Vakili, Henk Hoekstra, Maciej Bilicki +13
We present a sample of luminous red-sequence galaxies to study the large-scale structure in the fourth data release of the Kilo-Degree Survey. The selected galaxies are defined by…
KiDS-1000 catalogue: Redshift distributions and their calibration
H. Hildebrandt, J. L. van den Busch, A. H. Wright +15
We present redshift distribution estimates of galaxies selected from the fourth data release of the Kilo-Degree Survey over an area of deg (KiDS-1000). These redshif…
KiDS-1000 Cosmology: Cosmic shear constraints and comparison between two point statistics
Marika Asgari, Chieh-An Lin, Benjamin Joachimi +22
We present cosmological constraints from a cosmic shear analysis of the fourth data release of the Kilo-Degree Survey (KiDS-1000), doubling the survey area with nine-band optical a…
KiDS-1000 Cosmology: Multi-probe weak gravitational lensing and spectroscopic galaxy clustering constraints
Catherine Heymans, Tilman Tröster, Marika Asgari +31
We present a joint cosmological analysis of weak gravitational lensing observations from the Kilo-Degree Survey (KiDS-1000), with redshift-space galaxy clustering observations from…

We present weak lensing shear catalogues from the fourth data release of the Kilo-Degree Survey, KiDS-1000, spanning 1006 square degrees of deep and high-resolution imaging. Our `g…
KiDS-1000 Methodology: Modelling and inference for joint weak gravitational lensing and spectroscopic galaxy clustering analysis
B. Joachimi, C. -A. Lin, M. Asgari +24
We present the methodology for a joint cosmological analysis of weak gravitational lensing from the fourth data release of the ESO Kilo-Degree Survey (KiDS-1000) and galaxy cluster…
KiDS+VIKING+GAMA: Testing semi-analytic models of galaxy evolution with galaxy-galaxy-galaxy lensing
Laila Linke, Patrick Simon, Peter Schneider +9
Several semi-analytic models (SAMs) try to explain how galaxies form, evolve and interact inside the dark matter large-scale structure. These SAMs can be tested by comparing their…
