Pure-mode correlation functions for cosmic shear and application to KiDS-1000
Peter Schneider, Marika Asgari, Yasaman Najafi Jozani +10
One probe for systematic effects in gravitational lensing surveys is the presence of so-called B-modes in the cosmic shear two-point correlation functions ξ_\pm(\vt), since lensing…
High-quality strong lens candidates in the final Kilo Degree survey footprint
R. Li, N. R. Napolitano, C. Spiniello +16
We present 97 new high-quality strong lensing candidates found in the final , that completed the full area of the Kilo-Degree Survey (Ki…
AMICO galaxy clusters in KiDS-DR3: the impact of estimator statistics on the luminosity-mass scaling relation
Merijn Smit, Andrej Dvornik, Mario Radovich +4
As modern-day precision cosmology aims for statistical uncertainties of the percent level or lower, it becomes increasingly important to reconsider estimator assumptions at each st…
Joint constraints on cosmology and the impact of baryon feedback: combining KiDS-1000 lensing with the thermal Sunyaev-Zeldovich effect from Planck and ACT
Tilman Tröster, Alexander J. Mead, Catherine Heymans +13
We conduct a pseudo- analysis of the tomographic cross-correlation between 1000 deg of weak lensing data from the Kilo-Degree Survey (KiDS-1000) and the thermal Sunyaev…
The Weak Lensing Radial Acceleration Relation: Constraining Modified Gravity and Cold Dark Matter theories with KiDS-1000
Margot M. Brouwer, Kyle A. Oman, Edwin A. Valentijn +22
We present measurements of the radial gravitational acceleration around isolated galaxies, comparing the expected gravitational acceleration given the baryonic matter with the obse…
Geometry vs growth: Internal consistency of the flat ΛCDM model with KiDS-1000
J. Ruiz-Zapatero, Benjamin Stölzner, Benjamin Joachimi +11
We carry out a multi-probe self-consistency test of the flat CDM model with the aim of exploring potential causes of the reported tensions between high- and low-redshift cosmolo…
Halo shapes constrained from a pure sample of central galaxies in KiDS-1000
Christos Georgiou, Henk Hoekstra, Konrad Kuijken +12
We present measurements of , the ratio of the aligned components of the projected halo and galaxy ellipticities, for a sample of central galaxies using weak gravitational lens…
Bright galaxy sample in the Kilo-Degree Survey Data Release 4: selection, photometric redshifts, and physical properties
M. Bilicki, A. Dvornik, H. Hoekstra +16
We present a bright galaxy sample with accurate and precise photometric redshifts (photo-zs), selected using photometry from the Kilo-Degree Survey (KiDS) Da…
