The Knotted Sky II: does BICEP2 require a nontrivial primordial power spectrum?

The Knotted Sky II: does BICEP2 require a nontrivial primordial power spectrum?

An inflationary gravitational wave background consistent with BICEP2 is difficult to reconcile with a simple power-law spectrum of primordial scalar perturbations. Tensor modes contribute to the temperature anisotropies at multipoles with l∼
