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…
Weighing the Giants - III. Methods and Measurements of Accurate Galaxy Cluster Weak-Lensing Masses
Douglas E. Applegate, Anja von der Linden, Patrick L. Kelly +7
We report weak-lensing masses for 51 of the most X-ray luminous galaxy clusters known. This cluster sample, introduced earlier in this series of papers, spans redshifts 0.15 < z_cl…
Weighing the Giants II: Improved Calibration of Photometry from Stellar Colors and Accurate Photometric Redshifts
Patrick L. Kelly, Anja von der Linden, Douglas E. Applegate +10
We present improved methods for using stars found in astronomical exposures to calibrate both star and galaxy colors as well as to adjust the instrument flat field. By developing a…
Weighing the Giants - I. Weak-lensing masses for 51 massive galaxy clusters: project overview, data analysis methods and cluster images
Anja von der Linden, Mark T. Allen, Douglas E. Applegate +10
This is the first in a series of papers in which we measure accurate weak-lensing masses for 51 of the most X-ray luminous galaxy clusters known at redshifts 0.15<z<0.7, in order t…
