Noncommutative Geometry and the Primordial Dipolar Imaginary Power Spectrum

Understand

We argue that an anisotropic dipolar imaginary primordial power spectrum is possible within the framework of noncommutative space-times.

• We show that such a spectrum provides a good description of the observed dipole modulation in CMBR data.
• We extract the corresponding power spectrum from data.
• The dipole modulation is related to the observed hemispherical anisotropy in CMBR data, which might represent the first signature of quantum gravity.
