A Multimessenger Analysis of the High-Energy Milky Way: Source Populations Contribute Significantly to IceCube's Galactic Neutrino Flux
Alisha Roberts, Ilias Cholis, Dan Hooper +1
We perform a joint analysis of the high-energy neutrino emission observed from the Galactic Plane by IceCube and the diffuse ultra-high-energy gamma-ray emission measured by LHAASO…
Ultrahigh-Energy Gamma-Ray Sources Need Not Be Hadronic PeVatrons
Zachary Curtis-Ginsberg, Dan Hooper, Justin Vandenbroucke
Ultrahigh-energy gamma rays () have been detected from a handful of astrophysical sources. Due to the Klein-Nishina suppression of inverse Compton scattering…
The Impact of Muon and Pion Cooling on the Neutrino Spectrum of NGC 1068
Carlos Blanco, Dan Hooper, Tim Linden +1
The IceCube Neutrino Observatory has detected a flux of neutrinos from the active galaxy, NGC 1068. The soft spectral index of these neutrinos has previous…
Searching for Synchrotron Emission from the Geminga TeV Halo using the Planck Satellite
Dan Hooper, Elena Pinetti, Anastasia Sokolenko
Pulsars convert a significant fraction of their total spin-down power into very high-energy electrons, leading to the formation of TeV halos. It is not yet known, however, whether…
Unraveling TeV Halos with the Cherenkov Telescope Array
Dan Hooper, Elena Pinetti, Anastasia Sokolenko
Pulsars are observed to emit bright and spatially extended emission at multi-TeV energies. Although such "TeV halos" appear to be an approximately universal feature of middle-aged…
