Abstract

Top-end cosmic rays The origin of ultrahigh-energy cosmic rays is one of the most profound mysteries in high-energy astrophysics. No standard supernovae, pulsars or black holes can accelerate particles to such enormous energies, so various exotic sources have been proposed. An obstacle to identifying the source is the difficulty of finding out what particles are actually present in the rays: once they enter the Earth's atmosphere they lose their original identity, producing a shower of elementary particles travelling close to the speed of light. A collaboration between radio astronomers and particle physicists may offer a new way of learning more about the nature and structure of ultrahigh-energy cosmic rays. Using low-cost radio receivers it is possible to detect radio flashes coincident with cosmic-ray air showers. The radiation can be explained by the geosynchrotron effect. With radio telescopes and particle detectors trained on the incoming rays, their structure may soon be revealed.
