Effect of Measurement Errors on Predicted Cosmological Constraints from Shear Peak Statistics with LSST

D. Bard, J. M. Kratochvil, C. Chang +26

The statistics of peak counts in reconstructed shear maps contain information beyond the power spectrum, and can improve cosmological constraints from measurements of the power spe…

Atmospheric PSF Interpolation for Weak Lensing in Short Exposure Imaging Data

C. Chang, P. J. Marshall, J. G. Jernigan +25

A main science goal for the Large Synoptic Survey Telescope (LSST) is to measure the cosmic shear signal from weak lensing to extreme accuracy. One difficulty, however, is that wit…
