CFHTLenS revisited: assessing concordance with Planck including astrophysical systematics

Abstract:

We investigate the impact of astrophysical systematics on cosmic shear cosmological parameter constraints from the Canada–France–Hawaii Telescope Lensing Survey (CFHTLenS) and the concordance with cosmic microwave background measurements by Planck. We present updated CFHTLenS cosmic shear tomography measurements extended to degree scales using a covariance calibrated by a new suite of N-body simulations.We analyse these measurements with a new model fitting pipeline, accounting for key system...
