Probing extreme astrophysical accelerators through large-scale neutrino anisotropy

We present the extent to which large-scale anisotropies in the ultrahigh energy neutrino sky can probe the distribution of extreme astrophysical accelerators in the universe. In this talk, we discuss the origin of a large-scale neutrino anisotropy and show how observers can use this anisotropy to measure the evolution of ultrahigh energy neutrino sources — and therefore, the sources of ultrahigh energy cosmic rays — for the very first time.
