Separating cosmic shear from intrinsic galaxy alignments: Correlation function tomography
Separating cosmic shear from intrinsic galaxy alignments: Correlation function tomography
During the past few years, secure detections of cosmic shear have been obtained, manifest in the correlation of the observed ellipticities of galaxies. Constraints have already been placed on cosmological parameters, such as the normalisation of the matter power spectrum . One possible systematic contaminant of the lensing correlation signal …
