Who they are
Jocelyn Bell Burnell identified unusual signals while operating a radio telescope as a graduate researcher. Her follow-up recordings resolved rapidly repeating pulses, and work with colleagues tested interference and possible source explanations. Her retrospective account preserves both the observing sequence and the contributions of the wider team behind the pulsar discovery.
She represents the careful recognition and testing of an unexpected astronomical signal.

Little Green Men, White Dwarfs or Pulsars?
Bell Burnell recounts identifying the repeating pulses and the subsequent checks by Hewish and other collaborators. Her retrospective separates telescope operation, recognition of the signal, timing analysis and independent checks.
Cosmic Search reprint, January 1979; the page identifies an earlier December 1977 publication as “Petit Four.”
Reading scope & citation
Freshly read the discovery narrative and publication note; historical recollection, not raw observing records. Reuses the input’s documented prior inspection: Discovery-sequence passages and reprint provenance inspected; account originated as a speech published December 1977. No fresh full-work reread in this directory pass. Existing discovery-sequence inspection reused; fresh page heading and provenance read. Original recordings and full 1968 discovery paper not audited.
