LARGE SCALE FLOWS: IMPLICATIONS FOR INFLATION

摘要

We have recently measured a coherent bulk scale flow that encompasses ～ 300Mpc/h of amplitude 600 - 1000km/s in the direction of the cosmic CMB dipole. This bulk flow motion is very difficult to accomodate within the standard ΛCDM cosmological model. We shall summarize the results and its implications for cosmology, discussing possible explanations such a large scale void or a residual superhorizon fluctuation and their implications for inflation and/or quantum cosmology.
