Measuring the dark universe with gravitational lensing

Abstract:

This thesis presents the use of gravitational lensing as a measure of the large-scale structure in the Universe. We detail various statistical techniques for performing and interpreting these measurements. We show evidence for the cross-correlation of cosmic microwave background (CMB) lensing with the positions of radio-loud active galactic nuclei (AGN). We demonstrate a weak- lensing cross-correlation pipeline for combining cosmic shear measurements with CMB lensing data. We forecast how ...
