An adapted filter function for density split statistics in weak lensing
Pierre Burger, Peter Schneider, Vasiliy Demchenko +4
Context. The density split statistics in weak gravitational lensing analyses probes the correlation between regions of different (foreground) galaxy number densities and their weak…
KiDS-Legacy: Cosmological constraints from cosmic shear with the complete Kilo-Degree Survey
Angus H. Wright, Benjamin Stölzner, Marika Asgari +35
We present cosmic shear constraints from the completed Kilo-Degree Survey (KiDS), where the cosmological parameter , i…
A revised density split statistic model for general filters
Pierre Burger, Oliver Friedrich, Joachim Harnois-Déraps +1
Studying the statistical properties of the large-scale structure in the Universe with weak gravitational lensing is a prime goal of several current and forthcoming galaxy surveys.…
KiDS-1000: Detection of deviations from a purely cold dark matter power spectrum with tomographic weak gravitational lensing
Patrick Simon, Lucas Porth, Pierre Burger +1
Model uncertainties in the non-linear structure growth limit current probes of cosmological parameters. To shed more light on the physics of non-linear scales, we reconstructed the…
KiDS-1000 and DES-Y1 combined: Cosmology from peak count statistics
Joachim Harnois-Deraps, Sven Heydenreich, Benjamin Giblin +10
We analyse the fourth data release of the Kilo Degree Survey (KiDS-1000) and extract cosmological parameter constraints based on the cosmic shear peak count statistics. Peaks are i…
KiDS-Legacy: Consistency of cosmic shear measurements and joint cosmological constraints with external probes
Benjamin Stölzner, Angus H. Wright, Marika Asgari +33
We present a cosmic shear consistency analysis of the final data release from the Kilo-Degree Survey (KiDS-Legacy). By adopting three tiers of consistency metrics, we compare cosmo…
