This paper describes further mass measurements of a particular merging cluster system, the "Bullet Cluster," showing how gravitational lensing can be used to measure the mass of a structure that is not in dynamical equilibrium, and without assuming that "mass follows light." Strong lensing information is combined in a joint analysis, improving the accuracy of the mass peak positions.

This paper presents results from a combination of 4 blank-field surveys to achieve a 100 square degree total area, and contains a good discussion on how errors in Point Spread Function correction and background galaxy selection can propagate through to the cosmic-shear measurement. (A)

This paper describes measurements of cosmic shear from a 2 square degree Hubble Space Telescope survey, combined with photometric redshifts of the lensed galaxies. The addition of the photometric redshifts allowed the authors to measure the evolution of the mass power-spectrum, which provides additional information about the cosmological model beyond what the integrated power-spectrum can provide.

The sources behind Zwicky's proposed lenses would be galaxies and their active nuclei, in the far distant universe; only in the last 30 years have such faint objects been detected in sufficient numbers to reveal the one in a thousand that are multiply-imaged. The first lensed quasar was confirmed in this paper. (A)

The deflection of during an eclipse was the first observation of lensing in the universe, but there would not be another for 60 years. However, in the 1930s, Fritz Zwicky predicted that galaxies and clusters of galaxies would make good gravitational lenses as well, in this prescient paper. (A)

This review contains an extremely in-depth discussion of the basics of weak gravitational lensing, with full mathematical derivations of all of the concepts known as of 2000. This review is an excellent starting point for a graduate student wanting to learn the details of weak lensing observations and theory. This review allows us to limit the number of introductory papers in the following sections and concentrate on papers giving more recent developments in the field (A).
