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 (simon.samuroff@postgrad.manchester.ac.uk).

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 (lise@slac.stanford.edu) or Tim Eifler (tim.eifler@jpl.nasa.gov).

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 (troxel.18@osu.edu).

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 (kadrlica@fnal.gov).

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 (jprat@ifae.es) or Carles Sanchez (csanchez@ifae.es).
