Our paper on the GRAND prototype arrays is finally out!

GRAND, the Giant Radio Array for Neutrino Detection, is an envisioned next-generation observatory for the detection of ultra-high-energy cosmic rays, gamma rays, and, especially, neutrinos.

For the past two years, three small-scale GRAND prototype arrays have been running to test the technology and detection principle of the experiment: GRAND@Nançay in France, GRAND@Auger in Argentina, and GRANDProto300 in China.

This paper was led by Beatriz de Errico, from the Federal University of Rio de Janeiro, and Shen Wang, from Purple Mountain Observatory.
