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".\r\n 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-periodicities, 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.

本提案关联于提交至ATCA的一项相似提案，题为："揭开神秘脉冲星PSR J1926-06的奥秘"
我们提议利用帕克斯望远镜（Parkes telescope）配备的超宽带低频接收器，量化新发现脉冲星PSR J1926-06的宽带间歇性时标、偏振特性、准周期性及模式转换。该脉冲星的发射特性独具一格：其多脉冲成分随时间动态变化（模式转换与子脉冲漂移现象显著），存在零射电现象（部分单个脉冲缺失），还表现出更长时间尺度（小时级）的间歇性发射中断行为，且脉冲流量密度常呈现准周期性变化（但并非始终如此）。显然，该脉冲星或为破解多种发射现象之谜的关键，因此我们申请使用帕克斯望远镜、FAST及ATCA的观测时间，对其及发射特性展开详细参数化研究。
