Free-Streaming Neutrinos and Their Phase Shift in Current and Future CMB Power Spectra
Gabriele Montefalcone, Benjamin Wallisch, Katherine Freese
The cosmic neutrino background and other light relics leave distinct imprints in the cosmic microwave background anisotropies through their gravitational influence. Since neutrinos…
