Grand Unified Neutrino Spectrum at Earth: Sources and Spectral Components

Understand

We briefly review the dominant neutrino fluxes at Earth from different sources and present the Grand Unified Neutrino Spectrum ranging from meV to PeV energies.

• For each energy band and source, we discuss both theoretical expectations and experimental data.
• This compact review should be useful as a brief reference to those interested in neutrino astronomy, fundamental particle physics, dark-matter detection, high-energy astrophysics, geophysics, and other related topics.
