TL;DR: In this article, the authors present cosmological parameter constraints from a tomographic weak gravitational lensing analysis of ~450deg$^2$ of imaging data from the Kilo Degree Survey (KiDS) for a flat Lambda$CDM cosmology with a prior on $H_0$ that encompasses the most recent direct measurements.

TL;DR: In this paper, the authors conducted a redshift survey of eight low-redshift clusters (APMCC0917, A168, A4038, EDCC442, A3880, A2399, A119 and A85) using the AAOmega multi-object spectrograph on the 3.9m Anglo-Australian Telescope.
