Title: Lensing measurements of galaxies and voids

 

Abstract:

  I will show weak lensing results from the Sloan Digital Sky Survey and the Dark Energy Survey. From Sloan data we use new methods to measure the mass distribution and clustering of cosmic voids and the shapes of galaxy halos. With the Dark Energy Survey, we have made wide field mass maps and related the galaxy distribution to the lensing mass, including CMB lensing.
