Constraining the spectrum of cosmological perturbations from statistical thermal fluctuations
In the standard inflationary paradigm, the seeds for cosmic structures are assumed to be of quantum origin. During inflation, the quantum fluctuations of the fields are stretched by the cosmic expansion to macroscopic sizes and become classical, then growing through gravitational collapse to eventua...
