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…
