The Spectroscopic Stage-5 Experiment
Robert Besuner, Arjun Dey, Alex Drlica-Wagner +106
The existence, properties, and dynamics of the dark sectors of our universe pose fundamental challenges to our current model of physics, and large-scale astronomical surveys may be…
Selection Function of Clusters in Dark Energy Survey Year 3 Data from Cross-Matching with South Pole Telescope Detections
S. Grandis, M. Costanzi, J. J. Mohr +52
Galaxy clusters selected based on overdensities of galaxies in photometric surveys provide the largest cluster samples. Yet modeling the selection function of such samples is compl…
Dark Energy Survey Year 6 Results: Point-spread Function Modeling
T. Schutt, M. Jarvis, A. Roodman +70
We present the point-spread function (PSF) modeling for weak lensing shear measurement using the full six years of the Dark Energy Survey (DES Y6) data. We review the PSF estimatio…
Dark Energy Survey Year 6 Results: Synthetic-source Injection Across the Full Survey Using Balrog
D. Anbajagane, M. Tabbutt, J. Beas-Gonzalez +79
Synthetic source injection (SSI), the insertion of sources into pixel-level on-sky images, is a powerful method for characterizing object detection and measurement in wide-field, a…
Dark Energy Survey Year 6 Results: Cell-based Coadds and Metadetection Weak Lensing Shape Catalogue
M. Yamamoto, M. R. Becker, E. Sheldon +81
We present the Metadetection weak lensing galaxy shape catalogue from the six-year Dark Energy Survey (DES Y6) imaging data. This dataset is the final release from DES, spanning 44…
Multiprobe Cosmology from the Abundance of SPT Clusters and DES Galaxy Clustering and Weak Lensing
S. Bocquet, S. Grandis, E. Krause +216
Cosmic shear, galaxy clustering, and the abundance of massive halos each probe the large-scale structure of the Universe in complementary ways. We present cosmological constraints…
