Universality classes are not that universal (…and some of its other shortcomings)

Article: Shortcomings of New Parameterizations of Inflation Authors: J. Martin, C. Ringeval and V. Vennin Reference: arXiv:1609.04739 The Cosmic Microwave Background radiation (CMB) is an amazingly simple and beautiful picture that is pivotal for observational cosmology. It is the oldest light in our Universe: it originates from when the Universe was only a sprightly 380,000 years […]
