TL;DR: Using a new survey of more than 10,000 faint galaxies, the anisotropy parameter β = 0.70 ± 0.26 is measured, which is consistent with the standard cosmological-constant model with low matter density and flat geometry, although the error bars are still too large to distinguish among alternative origins for the accelerated expansion.
