First Cosmology Results Using Type Ia Supernovae from the Dark Energy Survey: Effects of Chromatic Corrections to Supernova Photometry on Measurements of Cosmological Parameters
J. Lasker, R. Kessler, D. Scolnic +78
Calibration uncertainties have been the leading systematic uncertainty in recent analyses using type Ia Supernovae (SNe Ia) to measure cosmological parameters. To improve the calib…
Steve: A hierarchical Bayesian model for Supernova Cosmology
S. R. Hinton, T. M. Davis, A. G. Kim +66
We present a new Bayesian hierarchical model (BHM) named Steve for performing type Ia supernova (SNIa) cosmology fits. This advances previous works by including an improved treatme…
First Cosmology Results Using Type Ia Supernovae From the Dark Energy Survey: Analysis, Systematic Uncertainties, and Validation
D. Brout, D. Scolnic, R. Kessler +122
We present the analysis underpinning the measurement of cosmological parameters from 207 spectroscopically classified type Ia supernovae (SNe Ia) from the first three years of the…
First Cosmological Results using Type Ia Supernovae from the Dark Energy Survey: Measurement of the Hubble Constant
E. Macaulay, R. C. Nichol, D. Bacon +106
We present an improved measurement of the Hubble constant (H_0) using the 'inverse distance ladder' method, which adds the information from 207 Type Ia supernovae (SNe Ia) from the…
First Cosmology Results using Type Ia Supernovae from the Dark Energy Survey: Constraints on Cosmological Parameters
T. M. C. Abbott, S. Allam, P. Andersen +141
We present the first cosmological parameter constraints using measurements of type Ia supernovae (SNe Ia) from the Dark Energy Survey Supernova Program (DES-SN). The analysis uses…
Dark Energy Survey Year 1 Results: Methods for Cluster Cosmology and Application to the SDSS
M. Costanzi, E. Rozo, M. Simet +83
We perform the first blind analysis of cluster abundance data. Specifically, we derive cosmological constraints from the abundance and weak-lensing signal of \redmapper\ clusters o…
Survey geometry and the internal consistency of recent cosmic shear measurements
M. A. Troxel, E. Krause, C. Chang +76
We explore the impact of an update to the typical approximation for the shape noise term in the analytic covariance matrix for cosmic shear experiments that assumes the absence of…
Dark Energy Survey Year 1 Results: Methodology and Projections for Joint Analysis of Galaxy Clustering, Galaxy Lensing, and CMB Lensing Two-point Functions
E. J. Baxter, Y. Omori, C. Chang +91
Optical imaging surveys measure both the galaxy density and the gravitational lensing-induced shear fields across the sky. Recently, the Dark Energy Survey (DES) collaboration used…
Dark Energy Survey Year 1 Results: Weak Lensing Shape Catalogues
J. Zuntz, E. Sheldon, S. Samuroff +104
We present two galaxy shape catalogues from the Dark Energy Survey Year 1 data set, covering 1500 square degrees with a median redshift of . The catalogues cover two main fie…
Space Warps II. New Gravitational Lens Candidates from the CFHTLS Discovered through Citizen Science
Anupreeta More, Aprajita Verma, Philip J. Marshall +18
We report the discovery of 29 promising (and 59 total) new lens candidates from the CFHT Legacy Survey (CFHTLS) based on about 11 million classifications performed by citizen scien…
Orientation Bias of Optically Selected Galaxy Clusters and Its Impact on Stacked Weak Lensing Analyses
Jörg P. Dietrich, Yuanyuan Zhang, Jeeseon Song +15
Weak-lensing measurements of the averaged shear profiles of galaxy clusters binned by some proxy for cluster mass are commonly converted to cluster mass estimates under the assumpt…
