Parkes observations for project P863 semester 2017OCTS

In this proposal we request observations from the Parkes radio telescope to survey the complete sample of intermittent pulsars. These are pulsars whose emission switches on and off at seemingly random intervals. We plan to use the dual-band, multibeam and the H-OH receivers that will provide us with information at widely separated frequency bands. We will determine the distribution of the time scales, calculate spin-down rates, look for weak or bursty emission in the "off" states and determine the bandwidth of the on/off emission process and relate these results to predictions from recent theoretical models.

在本提案中，我们申请使用帕克斯射电望远镜开展观测，以对间歇性脉冲星（intermittent pulsars）的完整样本进行巡天。这类脉冲星的辐射会在看似随机的时间间隔内开启与关闭。我们计划采用双波段、多波束及H-OH接收器，这些设备将为我们提供间隔较大频段的信息。我们将确定时间尺度的分布，计算自旋减慢速率（spin-down rate），寻找“关闭”状态下的微弱或爆发式辐射，并确定开关辐射过程的带宽，进而将这些结果与近期理论模型的预测相关联。
