Probing the PeV Region in the Astrophysical Neutrino Spectrum using $\hat{I}{½}_{\hat{I}}¼$ from the Southern Sky

R. Abbasi, M. Ackermann, J. Adams +425

IceCube has observed a diffuse astrophysical neutrino flux over the energy region from a few TeV to a few PeV. At PeV energies, the spectral shape is not yet well measured due to t…
