Validation of PSF Models for HST and Other Space-Based Observations
Bryan R. Gillis, Tim Schrabback, Ole Marggraf +4
Forthcoming space-based observations will require high-quality point-spread function (PSF) models for weak gravitational lensing measurements. One approach to generating these mode…
The Effects of Calibration on the Bias of Shear Measurements
Bryan R. Gillis, A. N. Taylor
Forthcoming large-scale surveys will soon attempt to measure cosmic shear to an unprecedented level of accuracy, requiring a similarly high level of accuracy in the shear measureme…
Calibration of colour gradient bias in shear measurement using HST/CANDELS data
Xinzhong Er, Henk Hoekstra, Tim Schrabback +6
Accurate shape measurements are essential to infer cosmological parameters from large area weak gravitational lensing studies. The compact diffraction-limited point-spread function…
A Generalized Method for Measuring Weak Lensing Magnification With Weighted Number Counts
Bryan Gillis, Andy Taylor
We present a derivation of a generalized optimally-weighted estimator for the weak lensing magnification signal, including a calculation of errors. With this estimator, we present…
