Abstract

We present cosmological parameter constraints from a tomographic weak gravitational lensing analysis of ∼450 deg2 of imaging data from the Kilo Degree Survey (KiDS). For a flat ΛCDM cosmology with a prior on H0 that encompasses the most recent direct measurements, we find \nS8≡σ8Ωm/0.3−−−−−−√=0.745±...
