Constraining the phase shift of relativistic species in DESI BAOs
Abbé M. Whitford, Hugo Rivera-Morales, Cullan Howlett +36
In the early Universe, neutrinos decouple quickly from the primordial plasma and propagate without further interactions. The impact of free-streaming neutrinos is to create a tempo…
