Role of dense matter in collective supernova neutrino transformations
A. Esteban-Pretel, A. Mirizzi, S. Pastor +4
For neutrinos streaming from a supernova (SN) core, dense matter suppresses self-induced flavor transformations if the electron density n_e significantly exceeds the neutrino densi…
Ultrahigh energy cosmic rays as heavy nuclei from cluster accretion shocks
Susumu Inoue, Guenter Sigl, Francesco Miniati +1
Large-scale accretion shocks around massive clusters of galaxies, generically expected in hierarchical scenarios of cosmological structure formation, are shown to be potential sour…
Effects of Axion-Photon Mixing on Gamma-Ray Spectra from Magnetized Astrophysical Sources
Kathrin A. Hochmuth, Guenter Sigl
Astrophysical gamma-ray sources come in a variety of sizes and magnetizations. We deduce general conditions under which gamma-ray spectra from such sources would be significantly a…
Lorentz Violation for Photons and Ultra-High Energy Cosmic Rays
Matteo Galaverni, Guenter Sigl
Lorentz symmetry breaking at very high energies may lead to photon dispersion relations of the form omega^2=k^2+xi_n k^2(k/M_Pl)^n with new terms suppressed by a power n of the Pla…
