Detecting Neutrino Emission from Supernova Remnants: A Theoretically Motivated Target Catalog
Emily Simon, Rebecca Diesing, Damiano Caprioli +1
Galactic supernova remnants (SNRs) are thought to accelerate cosmic rays (CRs) to several PeV energies, but this has yet to be confirmed as general behavior. Although several sourc…

A "Faux-Shock" Method for Hybrid Simulations of Astrophysical Shocks
Emily R. Simon, Damiano Caprioli, Colby C. Haggerty +1
We demonstrate a novel setup for hybrid particle-in-cell simulations designed to isolate the physics of the shock precursor over long time periods for significantly lower computati…

Searching For Superheavy Decaying Particles With Ultra-High-Energy Neutrino Observatories
Kim V. Berghaus, Dan Hooper, Emily R. Simon
If there exist unstable but long-lived relics of the early universe, their decays could produce detectable fluxes of gamma rays and neutrinos. In this paper, we point out that the…
