Andrej Dvornik and Constance Mahony tell us about the Kilo-Degree Survey (KiDS) and their progress at probing the non-linear scales with data from the survey.

Constance talks about her recent paper showing that non-linear halo bias is absolutely necessary if you want to avoid errors larger than 5σ on the small, non-linear scales.

Andrej takes this and does the analysis on KiDS data to obtain cosmological constraints.
