Query: Scale-dependent CMB asymmetry from primordial configuration   We demonstrate that a topological defect can explain the hemispherical power
asymmetry of the CMB. The first point is that a defect configuration, which
already exists prior to inflation, can source asymmetry of the CMB. The second
point is that modulation mechanisms, such as the curvaton and other modulation
mechanisms, can explain scale-dependence of the asymmetry. Using a simple
analysis of the $\delta N$ formalism, we show models in which scale-dependent
hemispherical power asymmetry is explained by primordial configuration of a
defect.
