Dark Matter Distribution of Four Low-z Clusters of Galaxies
  We present here the weak gravitational lensing detection of four nearby
galaxy clusters in the southern sky: Abell 2029, Abell 85, Abell 1606 and Abell
2457. The weak lensing detections of Abell 1606 and Abell 2457 are the first in
the literature. This work capitalizes on the wide field of view of the Dark
Energy Camera at the Cerro Tololo Inter-American Observatory, which we use to
obtain deep, multi-wavelength imaging of all targets. We publish maps of the
clusters' projected mass distributions, and obtain the $M_{200}$ of their
clusters through NFW profile fits to the two-dimensional tangential ellipticity
signal.
