Antony Hewish (1924–2021)

Hewish realized that a large array designed to detect low-frequency scintillation would address three important astronomical problems: the discovery of many more radio quasars; the measurement of their angular sizes; and the determination of the structure and velocity of the solar wind, the stream o...

Description
Summary:Hewish realized that a large array designed to detect low-frequency scintillation would address three important astronomical problems: the discovery of many more radio quasars; the measurement of their angular sizes; and the determination of the structure and velocity of the solar wind, the stream of charged particles flowing out of the Sun. The discovery of neutron stars by this radio technique - they were much too faint to be detected by optical telescopes - came as a complete surprise. In the years after, other researchers detected many radio pulsars, including in binary neutron-star systems that provided precision tests of general relativity.
