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…
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…
KiDS-1000 catalogue: Weak gravitational lensing shear measurements
Benjamin Giblin, Catherine Heymans, Marika Asgari +19
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+GAMA: The weak lensing calibrated stellar-to-halo mass relation of central and satellite galaxies
Andrej Dvornik, Henk Hoekstra, Konrad Kuijken +13
We simultaneously present constraints on the stellar-to-halo mass relation for central and satellite galaxies through a weak lensing analysis of spectroscopically classified galaxi…
The effects of varying depth in cosmic shear surveys
Sven Heydenreich, Peter Schneider, Hendrik Hildebrandt +7
We present a semi-analytic model for the shear two-point correlation function of a cosmic shear survey with non-uniform depth. Ground-based surveys are subject to depth variations…
KiDS+VIKING-450 and DES-Y1 combined: Mitigating baryon feedback uncertainty with COSEBIs
Marika Asgari, Tilman Tröster, Catherine Heymans +12
We present cosmological constraints from a joint cosmic shear analysis of the Kilo-Degree Survey (KV450) and the Dark Energy Survey (DES-Y1), conducted using Complete Orthogonal Se…
Cosmology from large-scale structure: Constraining CDM with BOSS
Tilman Tröster, Ariel. G. Sánchez, Marika Asgari +9
We reanalyse the anisotropic galaxy clustering measurement from the Baryon Oscillation Spectroscopic Survey (BOSS), demonstrating that using the full shape information provides cos…
Quantifying systematics from the shear inversion on weak-lensing peak counts
Chieh-An Lin, Martin Kilbinger
Weak-lensing peak counts provide a straightforward way to constrain cosmology by linking local maxima of the lensing signal to the mass function. Recent applications to data have a…
Cosmology with weak-lensing peak counts
Chieh-An Lin
Weak gravitational lensing (WL) causes distortions of galaxy images and probes massive structures on large scales, allowing us to understand the late-time evolution of the Universe…
Cosmological constraints with weak lensing peak counts and second-order statistics in a large-field survey
Austin Peel, Chieh-An Lin, Francois Lanusse +3
Peak statistics in weak lensing maps access the non-Gaussian information contained in the large-scale distribution of matter in the Universe. They are therefore a promising complem…
A new model to predict weak-lensing peak counts III. Filtering technique comparisons
Chieh-An Lin, Martin Kilbinger, Sandrine Pires
This is the third in a series of papers that develop a new and flexible model to predict weak-lensing (WL) peak counts, which have been shown to be a very valuable non-Gaussian pro…
A new model to predict weak-lensing peak counts II. Parameter constraint strategies
Chieh-An Lin, Martin Kilbinger
Peak counts have been shown to be an excellent tool to extract the non-Gaussian part of the weak lensing signal. Recently, we developped a fast stochastic forward model to predict…
A new model to predict weak-lensing peak counts I. Comparison with -body Simulations
Chieh-An Lin, Martin Kilbinger
Weak-lensing peak counts has been shown to be a powerful tool for cosmology. It provides non-Gaussian information of large scale structures, complementary to second order statistic…
