Numerical Simulations of Weak Lensing Measurements
David Bacon, Alexandre Refregier, Douglas Clowe +1
(Abridged) Weak gravitational lensing induces distortions on the images of background galaxies, and thus provides a direct measure of mass fluctuations in the universe. Since the d…

Detection of Weak Gravitational Lensing by Large-scale Structure
David Bacon, Alexandre Refregier, Richard Ellis
We report a detection of the coherent distortion of faint galaxies arising from gravitational lensing by foreground structures. This ``cosmic shear'' is potentially the most direct…
