Euclid preparation: VI. Verifying the Performance of Cosmic Shear Experiments
Euclid Collaboration, P. Paykari, T. D. Kitching +128
Our aim is to quantify the impact of systematic effects on the inference of cosmological parameters from cosmic shear. We present an end-to-end approach that introduces sources of…
A KiDS weak lensing analysis of assembly bias in GAMA galaxy groups
Andrej Dvornik, Marcello Cacciato, Konrad Kuijken +19
We investigate possible signatures of halo assembly bias for spectroscopically selected galaxy groups from the GAMA survey using weak lensing measurements from the spatially overla…
KiDS-450: Testing extensions to the standard cosmological model
Shahab Joudaki, Alexander Mead, Chris Blake +16
We test extensions to the standard cosmological model with weak gravitational lensing tomography using 450 deg of imaging data from the Kilo Degree Survey (KiDS). In these exte…
KiDS-450: Cosmological parameter constraints from tomographic weak gravitational lensing
H. Hildebrandt, M. Viola, C. Heymans +33
We present cosmological parameter constraints from a tomographic weak gravitational lensing analysis of ~450deg of imaging data from the Kilo Degree Survey (KiDS). For a flat $…
Calibration of weak-lensing shear in the Kilo-Degree Survey
Ian Fenech Conti, Ricardo Herbonnet, Henk Hoekstra +3
We describe and test the pipeline used to measure the weak lensing shear signal from the Kilo Degree Survey (KiDS). It includes a novel method of `self-calibration' that partially…
Gravitational Lensing Analysis of the Kilo Degree Survey
Konrad Kuijken, Catherine Heymans, Hendrik Hildebrandt +32
The Kilo-Degree Survey (KiDS) is a multi-band imaging survey designed for cosmological studies from weak lensing and photometric redshifts. It uses the ESO VLT Survey Telescope wit…
GREAT3 results I: systematic errors in shear estimation and the impact of real galaxy morphology
Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong +40
We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravi…
