Near-critical supernova outflows and their neutrino signatures
Alexander Friedland, Payel Mukhopadhyay
We demonstrate that the neutrino-driven outflows inside exploding core-collapse supernovae possess a special property of near-criticality, that is, they are on the edge of forming…
Halo Modification of a Supernova Neutronization Neutrino Burst
John F. Cherry, J. Carlson, Alexander Friedland +2
We give the first self-consistent calculation of the effect of the scattered neutrino halo on flavor evolution in supernovae. Our example case is an O-Ne-Mg core collapse supernova…
Galactic Streams of Cosmic-ray Electrons and Positrons
Matthew D. Kistler, Hasan Yuksel, Alexander Friedland
Isotropic diffusion is a key assumption in many models of cosmic-ray electrons and positrons. We find that simulation results imply a critical energy of ~10-1000~GeV above which el…
