Large-scale galaxy bias
This review presents a comprehensive overview of galaxy bias, that is, the statistical relation
between the distribution of galaxies and matter. We focus on large scales where cosmic …

Cosmology with cosmic shear observations: a review
M Kilbinger - Reports on Progress in Physics, 2015 - iopscience.iop.org
Cosmic shear is the distortion of images of distant galaxies due to weak gravitational lensing
by the large-scale structure in the Universe. Such images are coherently deformed by the …
