On minimally parametric primordial power spectrum reconstruction and the evidence for a red tilt
On minimally parametric primordial power spectrum reconstruction and the evidence for a red tilt
The latest cosmological data seem to indicate a significant deviation from scale invariance of the primordial power spectrum when parameterized either by a power law or by a spectral index with non-zero "running". This deviation, by itself, serves as a powerful tool to discriminate among theories for the origin of …
