Weak lensing using only galaxy position angles
Lee Whittaker, Michael L. Brown, Richard Battye
We develop a method for performing a weak lensing analysis using only measurements of galaxy position angles. By analysing the statistical properties of the galaxy orientations giv…
CFHTLenS tomographic weak lensing cosmological parameter constraints: Mitigating the impact of intrinsic galaxy alignments
Catherine Heymans, Emma Grocutt, Alan Heavens +21
We present a finely-binned tomographic weak lensing analysis of the Canada-France-Hawaii Telescope Lensing Survey, CFHTLenS, mitigating contamination to the signal from the presenc…
Planck 2013 results. XX. Cosmology from Sunyaev-Zeldovich cluster counts
Planck Collaboration, P. A. R. Ade, N. Aghanim +252
We present constraints on cosmological parameters using number counts as a function of redshift for a sub-sample of 189 galaxy clusters from the Planck SZ (PSZ) catalogue. The PSZ…
