Dark Energy Survey Year 1 Results: The Impact of Galaxy Neighbours on Weak Lensing Cosmology with IM3SHAPE

This paper uses simulated DES Y1 images to explore the impact of neighboring galaxies on galaxy shape measurements with im3shape and thereby on cosmology constraints from weak lensing cosmic shear. For more information, contact Simon Samuroff ([email protected]).

Dark Energy Survey Year 1 Results: Multi-Probe Methodology and Simulated Likelihood Analyses

This paper presents the methodology for combining the 3 measurements used in DES Y1 to derive cosmological constraints: galaxy clustering, galaxy-galaxy lensing, and cosmic shear. For more information, please contact Elisabeth Krause ([email protected]) or Tim Eifler ([email protected]).

Dark Energy Survey Year 1 Results: Cosmological Constraints from Cosmic Shear

This paper presents the most significant detection of weak gravitational lensing cosmic shear in a galaxy survey to date, using shapes of 26 million galaxies in 4 redshift bins, and derives constraints on cosmological parameters therefrom. This is one of the 3 measurements used in “Cosmological Constraints from Galaxy Clustering and Weak Lensing.” For more information, please contact Michael Troxel ([email protected]).

Dark Energy Survey Year 1 Results: Photometric Data Set for Cosmology

The Year 1 Gold catalog includes measurements of 137 million objects (galaxies and stars) in 5 filters (grizY) over 1800 square degrees of the sky. These data underlie many of the Year 1 cosmology results. For more information, contact Alex Drlica-Wagner ([email protected]).

Dark Energy Survey Year 1 Results: Galaxy-Galaxy Lensing

This paper presents measurements of the correlation of galaxy shear from 26 million source galaxies (from Zuntz, et al) with the positions of 660,000 red foreground lens galaxies (from Elvin-Poole, et al), due to weak gravitational lensing. This is one of the 3 data sets used in “Cosmological Constraints from Galaxy Clustering and Weak Lensing.” For more information, please contact Judit Prat ([email protected]) or Carles Sanchez ([email protected]).

Dark Energy Survey Year 1 Results: Cosmological Constraints from Galaxy Clustering and Weak Lensing

This paper combines DES Y1 measurements of galaxy clustering, galaxy-galaxy lensing, and weak lensing cosmic shear to derive constraints on cosmological parameters, compares with measurements from other experiments, and combines with external data to obtain stringent constraints. For more information, please contact the DES collaboration ([email protected]).

Dark Energy Survey Year 1 Results: Weak Lensing Shape Catalogues

This paper presents galaxy shape catalogues for the DES Y1 weak lensing measurements, using two independent shear measurement pipelines, Metacalibration and im3shape. These measurements are used in the Cosmic Shear analysis (Troxel, et al) and the Galaxy-galaxy lensing analysis (Prat, et al). For more information, please contact Joe Zuntz ([email protected]) or Erin Sheldon ([email protected]).

Dark Energy Survey Year 1 Results: Galaxy clustering for combined probes

This paper presents measurements of the spatial clustering of 660,000 red galaxies in 5 redshift bins and demonstrates robustness of the results against systematic errors. This is one of the 3 measurements used in “Cosmological Constraints from Galaxy Clustering and Weak Lensing.” For more information, please contact Jack Elvin-Poole ([email protected]).

Dark Energy Survey Year 1 Results: Curved-Sky Weak Lensing Mass Map

Using slight distortions of the shapes of 26 million distant galaxies due to weak gravitational lensing, DES scientists have constructed a map of the projected density of dark matter that spans several billion light years. For more information, contact Chihway Chang ([email protected]).
