Cosmological Constraints from the Kilo Degree Survey
ORAL · Invited
Abstract
I will present the latest tomographic cosmic shear measurements from the Kilo Degree Survey (KiDS), and the resulting cosmological parameter constraints. I will explore the sensitivity of the parameter constraints to the systematic uncertainties and improvements that come from incorporating overlapping near-infrared data from VIKING. I will also discuss the combined analysis of weak lensing tomography and overlapping redshift-space galaxy clustering from KiDS and the spectroscopic surveys of 2dFLenS, BOSS, and GAMA, with a focus on improvements to systematics mitigation and parameter constraints in standard and extended cosmologies.
*I acknowledge support from the Beecroft Trust and ERC 693024. KiDS is based on data from observations made with ESO Telescopes at the La Silla Paranal Observatory under programme IDs 177.A-3016, 177.A-3017 and 177.A-3018. 2dFLenS is based on data acquired through the Australian Astronomical Observatory, under program A/2014B/008.
