High-energy astrophysical neutrinos, with TeV--PeV energies, offer uniqueinsight into astrophysics and particle physics. Their incoming directions andflavor composition -- i.e., the proportion of electron, muon, and tau neutrinosin their flux -- are, individually, rewarding observables. Combined, they offernew opportunities, hitherto unexplored, that we expose for the first time.Anisotropy in the arrival directions of electron, muon, and tau neutrinos mayreveal multiple populations of neutrino sources, differently distributed in thesky, and test whether neutrinos of different flavor propagate preferentiallyalong certain directions, such as expected from breaking Lorentz invariance.Using 7.5 years of public IceCube High-Energy Starting Events, we make thefirst measurement of the directional flavor composition of high-energyastrophysical neutrinos, constrain the presence of flavor dipoles andquadrupoles, and improve constraints on "compass asymmetries" introduced byLorentz invariance violation. In the near future, upcoming neutrino telescopeswill improve these measurements across the board.
