  • New Early Dark Energy (NEDE) is a component of vacuum energy at the electron volt scale, which decays in a first order phase transition shortly before recombination [1]. The NEDE component has the potential to resolve the tension between recent local measurements of the expansion rate of the universe using supernovae (SN) data, and the expansion rate inferred from the early universe through measurements of the Cosmic Microwave Background (CMB) when assuming ΛCDM. We discuss in depth the two… CONTINUE READING
