Our study suggests the elusive ‘neutrino’ could make up a significant part of dark matter

In a new study, we revisit the tension between the constraints on Ωm and σ8 from the cosmic microwave background (CMB) and measurements of large-scale structure (LSS), using a large suite of cosmological computer simulations (called BAHAMAS) of normal and dark matter that also includes a treatment of massive neutrinos.
