Large Synoptic Survey Telescope: Dark Energy Science Collaboration
LSST Dark Energy Science Collaboration
This white paper describes the LSST Dark Energy Science Collaboration (DESC), whose goal is the study of dark energy and related topics in fundamental physics with data from the La…
Cosmological Calculations on the GPU
Deborah Bard, Matthew Bellis, Mark T. Allen +2
Cosmological measurements require the calculation of nontrivial quantities over large datasets. The next generation of survey telescopes (such as DES, PanSTARRS, and LSST) will yie…
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…
Spurious Shear in Weak Lensing with LSST
C. Chang, S. M. Kahn, J. G. Jernigan +25
The complete 10-year survey from the Large Synoptic Survey Telescope (LSST) will image 20,000 square degrees of sky in six filter bands every few nights, bringing the final…
