Ambiguities in gravitational lens models: impact on time delays of the source position transformation
Olivier Wertz, Bastian Orthen, Peter Schneider
The central ambition of the modern time delay cosmography consists in determining the Hubble constant with a competitive precision. However, the tension with obtained f…
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…
A comparison of the excess mass around CFHTLenS galaxy-pairs to predictions from a semi-analytic model using galaxy-galaxy-galaxy lensing
P. Simon, H. Saghiha, S. Hilbert +3
The matter environment of galaxies is connected to the physics of galaxy formation and evolution. Utilising galaxy-galaxy-galaxy lensing as a direct probe, we map out the distribut…
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-i-800: Comparing weak gravitational lensing measurements in same-sky surveys
A. Amon, C. Heymans, D. Klaes +21
We present a weak gravitational lensing analysis of 815 square degree of -band imaging from the Kilo-Degree Survey (KiDS--800). In contrast to the deep -band observations,…
