Research Abstract

We find that the evolution of gravitational potential of super-structures in accelerating universes plays an important role as a cause of claimed anomalies in the large-angle cosmic microwave background temperature anisotropy. In particular, the effects of low density regions with a radius of 200-300h/Mpc are most important and their abundance is at odd with the expected value in theΛCDM model at more than 3σlevel.
