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…
Maximal compression of the redshift space galaxy power spectrum and bispectrum
Davide Gualdi, Marc Manera, Benjamin Joachimi +1
We explore two methods of compressing the redshift space galaxy power spectrum and bispectrum with respect to a chosen set of cosmological parameters. Both methods involve reducing…
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…
Optimized Clustering Estimators for BAO Measurements Accounting for Significant Redshift Uncertainty
Ashley J. Ross, Nilanjan Banik, Santiago Avila +8
We determine an optimized clustering statistic to be used for galaxy samples with significant redshift uncertainty, such as those that rely on photometric redshifts. To do so, we s…
COLA with scale-dependent growth: applications to screened modified gravity models
Hans A. Winther, Kazuya Koyama, Marc Manera +2
We present a general parallelized and easy-to-use code to perform numerical simulations of structure formation using the COLA (COmoving Lagrangian Acceleration) method for cosmolog…
