Precise weak lensing constraints from deep high-resolution images: VLT/HAWK-I analysis of the super-massive galaxy cluster RCS2232727.7020437 at
Tim Schrabback, Mischa Schirmer, Remco F. J. van der Burg +16
We demonstrate that deep good-seeing VLT/HAWK-I images complemented with +-band photometry can yield a sensitivity for weak lensing studies of massive galaxy c…
KiDS-450: Cosmological Constraints from Weak Lensing Peak Statistics-I: Inference from Analytical Prediction of High Signal-to-Noise Ratio Convergence Peaks
HuanYuan Shan, Xiangkun Liu, Hendrik Hildebrandt +19
This paper is the first of a series of papers constraining cosmological parameters with weak lensing peak statistics using of imaging data from the Kilo Degree…
KiDS-450: Cosmological Constraints from Weak Lensing Peak Statistics - II: Inference from Shear Peaks using N-body Simulations
Nicolas Martinet, Peter Schneider, Hendrik Hildebrandt +12
We study the statistics of peaks in a weak lensing reconstructed mass map of the first 450 square degrees of the Kilo Degree Survey. The map is computed with aperture masses direct…
KiDS-450 + 2dFLenS: Cosmological parameter constraints from weak gravitational lensing tomography and overlapping redshift-space galaxy clustering
Shahab Joudaki, Chris Blake, Andrew Johnson +19
We perform a combined analysis of cosmic shear tomography, galaxy-galaxy lensing tomography, and redshift-space multipole power spectra (monopole and quadrupole) using 450 deg…
KiDS+GAMA: Cosmology constraints from a joint analysis of cosmic shear, galaxy-galaxy lensing and angular clustering
Edo van Uitert, Benjamin Joachimi, Shahab Joudaki +19
We present cosmological parameter constraints from a joint analysis of three cosmological probes: the tomographic cosmic shear signal in 450 deg of data from the Kilo Deg…
KiDS-450: The tomographic weak lensing power spectrum and constraints on cosmological parameters
F. Köhlinger, M. Viola, B. Joachimi +13
We present measurements of the weak gravitational lensing shear power spectrum based on sq. deg. of imaging data from the Kilo Degree Survey. We employ a quadratic estimator…
