The Random Magnetic Field of the Milky Way
Michael Unger, Glennys R. Farrar
We constrain the large-scale isotropic random component of the Galactic magnetic field using the Planck reconstruction of the 408 MHz synchrotron sky. Our analysis simultaneously f…

The Galactic Magnetic Field and UHECR Deflections
Michael Unger, Glennys R. Farrar
Ultrahigh-energy cosmic rays (UHECRs) experience deflections as they traverse the Galactic magnetic field (GMF), which must be accounted for when tracing them back to their sources…

The large-scale anisotropy and flux (de-)magnification of ultra-high-energy cosmic rays in the Galactic magnetic field
Teresa Bister, Glennys R. Farrar, Michael Unger
We calculate the arrival direction distribution of ultra-high-energy cosmic rays (UHECRs) with a new suite of models of the Galactic magnetic field (GMF), assuming sources follow t…
