Organised Randoms: Learning and correcting for systematic galaxy clustering patterns in KiDS using self-organising maps
Harry Johnston, Angus H. Wright, Benjamin Joachimi +10
We present a new method for the mitigation of observational systematic effects in angular galaxy clustering via corrective random galaxy catalogues. Real and synthetic galaxy data,…
Cosmic Shear Cosmology Beyond 2-Point Statistics: A Combined Peak Count and Correlation Function Analysis of DES-Y1
Joachim Harnois-Déraps, Nicolas Martinet, Tiago Castro +5
We constrain cosmological parameters from a joint cosmic shear analysis of peak-counts and the two-point shear correlation functions, as measured from the Dark Energy Survey (DES-Y…
Strong detection of the CMB lensingxgalaxy weak lensingcross-correlation from ACT-DR4,PlanckLegacy and KiDS-1000
Naomi Clare Robertson, David Alonso, Joachim Harnois-Déraps +48
We measure the cross-correlation between galaxy weak lensing data from the Kilo Degree Survey (KiDS-1000, DR4) and cosmic microwave background (CMB) lensing data from the Atacama C…
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…
Constraining cosmology with weak lensing voids
Christopher T. Davies, Marius Cautun, Benjamin Giblin +3
Upcoming surveys such as \LSST{} and \Euclid{} will significantly improve the power of weak lensing as a cosmological probe. To maximise the information that can be extracted from…
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

Testing gravity using galaxy-galaxy lensing and clustering amplitudes in KiDS-1000, BOSS and 2dFLenS
Chris Blake, Alexandra Amon, Marika Asgari +18
The physics of gravity on cosmological scales affects both the rate of assembly of large-scale structure, and the gravitational lensing of background light through this cosmic web.…
