The energy production rate & the generation spectrum of UHECRs
Boaz Katz, Ran Budnik, Eli Waxman
We derive simple analytic expressions for the flux and spectrum of ultra-high energy cosmic-rays (UHECRs) predicted in models where the CRs are protons produced by extra-Galactic s…

Magnetic field evolution in relativistic unmagnetized collisionless shocks
Uri Keshet, Boaz Katz, Anatoly Spitkovsky +1
We study relativistic unmagnetized collisionless shocks using unprecedentedly large particle-in-cell simulations of two-dimensional pair plasma. High energy particles accelerated b…

X-ray Hotspot Flares and Implications for Cosmic Ray Acceleration and Magnetic Field amplification in Supernova Remnants
Yousaf Butt, Troy Porter, Boaz Katz +1
For more than fifty years, it has been believed that cosmic ray (CR) nuclei are accelerated to high energies in the rapidly expanding shockwaves created by powerful supernova explo…
