…art in two billion, asymmetry of matter relative to antimatter whose origin is not known as of yet. The annihilation energy heated the photons but not the neutrinos. This left the neutrinos with a temperature that is 71.5% of the cosmic microwave background, corresponding to 1.95 degrees Kelvin above absolute zero today. Unfortunately, the characteristic energy of the relic neutrinos is too small for them to be directly detectable, even though their flux is ten times larger than that of Solar neutrinos.

CνB parameters could probably be constrained from data on the CMB polarization and vacuum birefringence near magnetars. The contribution of the dark sector neutrinos, however, might be nasty.
