TL;DR: Through simultaneous observations, synchronous switching in the radio and x-ray emission properties of pulsar PSR B0943+10 is detected, indicating rapid, global changes to the conditions in the magnetosphere, which challenge all proposed pulsar emission theories.

TL;DR: Radio measurements of Xmax with a mean uncertainty of 16 grams per square centimetre for air showers initiated by cosmic rays with energies of 1017–1017.5 electronvolts enable us to determine the mass spectrum of the cosmic rays: a mixed composition, with a light-mass fraction (protons and helium nuclei) of about 80 per cent.
