KiDS-450 + 2dFLenS: Cosmological parameter constraints from weak gravitational lensing tomography and overlapping redshift-space galaxy clustering

1 code implementation20 Jul 2017 Shahab Joudaki, Chris Blake, Andrew Johnson, Alexandra Amon, Marika Asgari, Ami Choi, Thomas Erben, Karl Glazebrook, Joachim Harnois-Deraps, Catherine Heymans, Hendrik Hildebrandt, Henk Hoekstra, Dominik Klaes, Konrad Kuijken, Chris Lidman, Alexander Mead, Lance Miller, David Parkinson, Gregory B. Poole, Peter Schneider, Massimo Viola, Christian Wolf

The complementarity of our observables allows for constraints on modified gravity degrees of freedom that are not simultaneously bounded with either probe alone, and up to a factor of three improvement in the $S_8$ constraint in the extended cosmology compared to KiDS alone.

The WiggleZ Dark Energy Survey: Direct constraints on blue galaxy intrinsic alignments at intermediate redshifts

Our null detection allows us to place upper limits on the contamination of weak lensing measurements by blue galaxy intrinsic alignments that, for the first time, do not require significant model-dependent extrapolation from the z~0. 1 SDSS observations.
