Results from a public shear simulation challenge that was specifically targeted for participation outside the weak lensing astronomical community. Also includes a summary of the results from the previous shear measurement challenges. (A)
First paper from the GREAT series of challenges, which attempt to understand systematics in shear measurements by gradually increasing the complexity of blind analysis simulations. More recent results can be found at http://greatchallenges.info (A)
Results from a large blind analysis study of shear measurements of galaxies. This paper contains good summaries of various methods to correct shear measurements for PSF smearing. (A)
This paper uses a large Hubble Space Telescope survey to obtain galaxy-galaxy lensing measurements at higher redshifts than previously possible, and explores the evolution of dark halo properties. (A)
This paper includes measurements of the ellipticity of dark-matter halos for different foreground galaxy properties. It includes a good discussion of potential systematic errors coming from intrinsic alignments of the background galaxies. (A)
This presents a galaxy-galaxy lensing study using a database large enough to subdivide the foreground galaxy sample by various properties, and still obtain a high signal-to-noise measurement of the mass profiles. (A)
A study of galaxy-galaxy lensing using a 45 square degree imaging survey, including the first significant attempt to measure the shape of the dark-matter halo by rotating (as well as translating) the background galaxy positions and shears to a common reference frame. (A)
This paper introduced the concept of galaxy-galaxy lensing, and provides scaling relations for predicting the number of background galaxies that will be needed to measure the mean mass profile around a given type of galaxy to a given accuracy. (A)
This paper studies how the distribution of faint, background galaxies is affected by the presence of bright, foreground galaxies, and models this as a product of weak lensing magnification. (A)
This paper studies the change in number density of quasars with distance from bright galaxies and models the results as a gravitational lensing signal from the bright galaxies. It includes a discussion of the potential systematic errors in the measurements and why previous attempts at making this measurement were limited by the systematic errors. (A)
This paper discusses the impact on cosmological-parameter measurement from cosmic-shear surveys owing to catastrophic errors in photometric redshifts measurements. (A)
This paper discusses the impact on cosmological-parameter measurement from cosmic-shear surveys owing to a variety of systematic errors. Of particular importance are the intrinsic alignments of galaxy shapes (prior to their being lensed) and the accuracy with which the lensed-galaxies redshifts can be estimated from their colors alone.

This paper discusses the impact on cosmological-parameter measurement from cosmic-shear surveys owing to the intrinsic alignments of galaxy shapes (prior to their being lensed). (A)
This paper describes how to use shear detected mass peaks to measure the evolution of the power spectrum, and thereby cosmological parameters, in a method complementary to cosmic-shear analysis. (A)
This paper describes how to use shear detected mass peaks to measure the evolution of the power spectrum, and thereby cosmological parameters, in a method complementary to cosmic-shear analysis. (A)
This paper describes an attempt to detect clusters by mass in a blank-field survey, thereby avoiding selection bias when measuring the evolution of the mass function. (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.
