Despite the remarkable success of the Λ Cold Dark Matter (ΛCDM) cosmological model, a growing discrepancy has emerged (currently measured at the level of ∼ 4 − 6σ) between the value of the Hubble constant H0 measured using the local distance ladder and the value inferred using the cosmic microwave background and galaxy surveys. While a vast array of ΛCDM extensions have been proposed to explain these discordant observations, understanding the (relative) success of these models in resolving the… Expand

Cosmology of an Axion-Like Majoron
We propose a singlet majoron model that defines an inverse seesaw mechanism in the ν sector. The majoron φ has a mass mφ ≈ 0.5 eV and a coupling to the τ lepton similar to the one to neutrinos. InExpand

In this letter we investigate the possibility that dark matter and (massive) neutrinos can interact via a simple, constant cross section. Building on previous numerical efforts, we constrain thisExpand
