Dark Energy Survey Year 1 Results: Measurement of the Baryon Acoustic Oscillation scale in the distribution of galaxies to redshift 1
The Dark Energy Survey Collaboration, T. M. C. Abbott, F. B. Abdalla +109
We present angular diameter distance measurements obtained by locating the BAO scale in the distribution of galaxies selected from the first year of Dark Energy Survey data. We con…
Covariance of the galaxy angular power spectrum with the halo model
Fabien Lacasa
As the determination of density fluctuations becomes more precise with larger surveys, it becomes more important to account for the increased covariance due to the non-linearity of…
Dark Energy Survey Year 1 Results: Cosmological Constraints from Galaxy Clustering and Weak Lensing
DES Collaboration, T. M. C. Abbott, F. B. Abdalla +197
We present cosmological results from a combined analysis of galaxy clustering and weak gravitational lensing, using 1321 deg of imaging data from the first year of the D…
Dark Energy Survey Year 1 Results: Multi-Probe Methodology and Simulated Likelihood Analyses
E. Krause, T. F. Eifler, J. Zuntz +83
We present the methodology for and detail the implementation of the Dark Energy Survey (DES) 3x2pt DES Year 1 (Y1) analysis, which combines configuration-space two-point statistics…
Inadequacy of internal covariance estimation for super-sample covariance
Fabien Lacasa, Martin Kunz
We give an analytical interpretation of how subsample-based internal covariance estimators lead to biased estimates of the covariance, due to underestimating the super-sample covar…
Combined analysis of galaxy cluster number count, thermal Sunyaev-Zel'dovich power spectrum, and bispectrum
G. Hurier, F. Lacasa
The Sunyaev-Zel'dovich (SZ) effect is a powerful probe of the evolution of structures in the universe, and is thus highly sensitive to cosmological parameters and , thou…
