The Pierre Auger Observatory is a hybrid detector, employing independent methods to detect and study the highest-energy cosmic rays. More than 400 scientists from 17 countries make up the International Collaboration in this institution.

“I totally agree that a neutron star merger is a promising candidate,” says Toshihiro Fujii, a particle astrophysicist at Osaka Metropolitan University who works with the Telescope Array, a huge cosmic ray detector in Dugway, Utah. Markus Roth, a particle astrophysicist at the Karlsruhe Institute of Technology who works on the Pierre Auger Observatory, an even bigger detector in Argentina, says, “I do not see any argument that would contradict [the] proposal.”
