Weak Gravitational Lensing Systematics from Image Combination
Charles Shapiro, Barnaby Rowe, Timothy Goodsall +5
Extremely accurate shape measurements of galaxy images are needed to probe dark energy properties with weak gravitational lensing surveys. To increase survey area with a fixed obse…
CFHTLenS: Co-evolution of galaxies and their dark matter haloes
Michael J. Hudson, Bryan R. Gillis, Jean Coupon +16
Galaxy-galaxy weak lensing is a direct probe of the mean matter distribution around galaxies. The depth and sky coverage of the CFHT Legacy Survey yield statistically significant g…
Initial results from a laboratory emulation of weak gravitational lensing measurements
Suresh Seshadri, Charles Shapiro, Timothy Goodsall +5
Weak gravitational lensing observations are a key science driver for the NASA Wide Field Infrared Survey Telescope (WFIRST). To validate the performance of the WFIRST infrared dete…
Sérsic galaxy models in weak lensing shape measurement: model bias, noise bias and their interaction
Tomasz Kacprzak, Sarah Bridle, Barnaby Rowe +4
Cosmic shear is a powerful probe of cosmological parameters, but its potential can be fully utilised only if galaxy shapes are measured with great accuracy. Two major effects have…
The Third Gravitational Lensing Accuracy Testing (GREAT3) Challenge Handbook
Rachel Mandelbaum, Barnaby Rowe, James Bosch +28
The GRavitational lEnsing Accuracy Testing 3 (GREAT3) challenge is the third in a series of image analysis challenges, with a goal of testing and facilitating the development of me…
Star/galaxy separation at faint magnitudes: Application to a simulated Dark Energy Survey
M. T. Soumagnac, F. B. Abdalla, O. Lahav +17
We address the problem of separating stars from galaxies in future large photometric surveys. We focus our analysis on simulations of the Dark Energy Survey (DES). In the first par…
