Weak lensing for precision cosmology
R Mandelbaum - Annual Review of Astronomy and Astrophysics, 2018 - annualreviews.org
Weak gravitational lensing, the deflection of light by mass, is one of the best tools to
constrain the growth of cosmic structure with time and reveal the nature of dark energy. I …
