Precision Projector Laboratory: Detector Characterization with an Astronomical Emulation Testbed
Charles Shapiro, Roger Smith, Eric Huff +7
As astronomical observations from space benefit from improved sensitivity, the effectiveness of scientific programs is becoming limited by systematics that often originate in poorl…
The DES Science Verification Weak Lensing Shear Catalogues
M. Jarvis, E. Sheldon, J. Zuntz +92
We present weak lensing shear catalogues for 139 square degrees of data taken during the Science Verification (SV) time for the new Dark Energy Camera (DECam) being used for the Da…
GalSim: The modular galaxy image simulation toolkit
Barnaby Rowe, Mike Jarvis, Rachel Mandelbaum +12
GALSIM is a collaborative, open-source project aimed at providing an image simulation tool of enduring benefit to the astronomical community. It provides a software library for gen…
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…
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…
Image Analysis for Cosmology: Results from the GREAT10 Star Challenge
T. D. Kitching, B. Rowe, M. Gill +13
We present the results from the first public blind PSF reconstruction challenge, the GRavitational lEnsing Accuracy Testing 2010 (GREAT10) Star Challenge. Reconstruction of a spati…
