Anisotropy in the matter distribution at very large scales
Tracing the cosmic evolution of the Baryonic Acoustic Oscillation (BAO) scale with galaxy two point correlation functions is currently the most promising approach to detect dark energy at early times. A number of ongoing and future experiments will measure the BAO peak with unprecedented accuracy. N-body simulations indicate that the matter distribution is anisotropic out to ~150 Mpc, far beyond the BAO scale of about 100 Mpc. I will discuss implications for the measurement of the BAO.
