Notes:
Radio pulsars were discovered in 1967 by Antony Hewish and his graduate student Jocelyn Bell-Burnell using the Cambridge radio telescope. Hewish subsequently received the Nobel Prize for this discovery. It was the first evidence of strictly periodic pulses seen on a chart recorder and it was speculated at the time that these were signals from other civilizations. As more and more pulsars were discovered it became clear however that a new class of object had been discovered.
The original paper was published by Hewish et al. In Nature, 1968, volume 217, p709.
