Abstract:
We measure shifts of the acoustic scale due to nonlinear growth andredshift distortions to a high precision using a very large volume ofhigh-force-resolution simulations. We compare results from various setsof simulations that differ in their force, volume, and mass resolution.We find a consistency within 1.5σ for shift values from differentsimulations and derive shift α(z) - 1 = (0.300 ± 0.015)
