Searching for a dipole modulation in the large-scale structure of the Universe

Understand

Several statistical anomalies in the CMB temperature anisotropies seem to defy the assumption of a homogeneous and isotropic universe.

• In particular, a dipole modulation has been detected both in WMAP and Planck data.
• We adapt the methodology proposed by Eriksen et al.
• (2007) on CMB data to galaxy surveys, tracing the large-scale structure.
