Weighing galaxy clusters with weak lensing magnification
Weak gravitational lensing is usually measured by quantifying the distortion of galaxy shapes. However, a different and complementary approach is to measure the magnification of distant background galaxies, which alters their observed number densities. I will give an introduction to lensing magnification, discuss recent progress made in this field, and show the results of applying this technique to measure stacked profiles of galaxy clusters in COSMOS and CFHTLenS.
