"Pulsar PSR J0026–1955: Astronomers Witness Subpulse Drifting and Nulling Phenomenon"

Astronomers have used the upgraded Giant Meterwave Radio Telescope (uGMRT) to observe the pulsar PSR J0026–1955, shedding light on its subpulse drifting and nulling behavior. The observations revealed unusual drifting behavior with both evolutionary and non-evolutionary drift rates, as well as the presence of short- and long-duration nulls. The study also found evidence of subpulse memory across nulls, suggesting the presence of an uninterrupted stable discharge in the polar gap during nulls. PSR J0026–1955 represents a small fraction of pulsars exhibiting these phenomena.
