Wild has played the leading part in the study of solar "bursts" in radio astronomy. These bursts are associated with the ejection by the sun of the clouds of "corpuscles" which cause terrestrial magnetic storms and of cosmic rays of solar origin. With his colleagues he has been responsible for the recognition of four out of the five types of burst now recognized as physically distinct. His discoveries of the occurrence of harmonics and of the systematic difference in apparent position at different frequencies have provided vital evidence on the mechanisms of origin. In this work he has pioneered two instrumental techniques, those of the dynamic radio spectrograph and the swept-frequency interferometer, which are now extensively used overseas.
