Backreaction and the Role of Spatial Curvature in the Cosmic Neighborhood
Average spatial curvature contributes about 10% to the local cosmic energy budget on scales up to 300 Mpc/h while kinematical backreaction stays below 1% on the smallest scales, with no convergence to the global Lambda-CDM model.
