Description
We present an updated analysis of cosmological models with very low reheating scenarios, where TRH∼O(MeV). Our study includes a more precise computation of neutrino distribution functions, leveraging the latest datasets from cosmological surveys. We perform a joint analysis that combines constraints from Big Bang Nucleosynthesis, the Cosmic Microwave Background, and galaxy surveys, alongside separate investigations of these datasets, carefully assessing the impact of different choices of priors. At the 95% confidence level, we establish a lower bound on the reheating temperature of TRH > 5.96 MeV, representing the most stringent constraint to date. Based on https://arxiv.org/abs/2501.01369
