| Description: | Drifting subpulses in PSR B0818-13. When zooming into the single pulses, many pulsars exhibit so-called 'secondary periodicities' - waves on waves. These 'drifting subpulses' are likely made by emitting structures (such as sparks or filaments) in the pulsar magnetosphere. The original data, from WSRT plus PuMaI, are Fig 1. in Janssen & van Leeuwen (2004) The poster was one of the entries in the Astronomy Pretty Poster Pageant (APPP) 2014. All entries are available for editing and outreach purposes within ASTRON. |
