Description

The Kilo-Degree Survey is providing a weak gravitational lensing tomography map of the large-scale structure back to redshift ~1. We recently completed observations. First results, based on 1/3 of the final data set, indicate that the large-scale structure is slightly smoother than predicted in the best-fit Planck 2018 cosmology. I will discuss the methodology that led to this result, in particular in relation to shape measurements and photometric redshifts, as well as the prospects from the ongoing final KiDS analyses and other surveys.
