Parkes observations for project P985 semester 2018OCTS_01
This proposal is linked with a similar proposal submitted to ATCA entitled: "Unraveling the mysteries of the enigmatic pulsar PSR J1926-06".
We propose to use the ultra-wide-bandwidth, low frequency receiver installed at the Parkes telescope in order to quantify the broad-band intermittency time scale, polarization, quasi-periodicitie... mores, and mode changing of a newly discovered pulsar, PSR J1926-06. The pulsar is unique in its emission properties. It has multiple pulse components, that change with time (both mode-changing and sub-pulse drifting phenomena are evident). The pulsar exhibits nulls in which a few individual pulses seem to be missing. It also exhibits longer-scale (hour-scale) intermittency behaviour in which the emission switches off for long periods of time. The pulse flux densities often, but not always, seem to exhibit quasi-periodic variations. Clearly this pulsar may hold the key to many different emission phenomena and we request time on Parkes, FAST and ATCA to parameterise the pulsar and its emission properties in detail. less

P985 - Characterising the Broad-band Intermittency Time Scale, Mode changing, Periodicities and Polarization Variations of PSR J1926-06
Pulsars are strange objects. One of the strangest was recently discovered by the 500-m telescope in China. This pulsar switches off and on. When on the emission seems to change in unexpected ways. We are proposing to use the new receiver system at Parkes in simultaneous observations with other telescopes in Australia and China to try and understand... more why this pulsar is acting so strangely. less
