Parkes observations for project P512 semester 2006OCTS_01

We propose to continue undertake a pulsar survey along the Galactic Plane using the new Methanol Multibeam receiver in order to uncover pulsars previously selected against in lower frequency surveys. The scientific aims of this survey are
(a) to discover young pulsars in the spiral arms, hidden at lower frequencies, (b) to improve our knowledge of the distribution of dispersing and scattering material, particularly in the inner Galaxy, (c) strike it lucky and discover unique objects (e.g. a pulsar with a black hole companion and short period binary pulsars) and
(d) to survey the transient radio sky at high frequencies. Simulations have shown that we expect to find a total of 200 pulsars of which about one half will be new detections.

本研究提出将借助新型甲醇多波束接收机（Methanol Multibeam receiver），沿银道面（Galactic Plane）开展持续性脉冲星巡天（pulsar survey），以发掘此前在低频巡天中被筛除的脉冲星。本次巡天的科学目标如下：
(a) 发现隐藏于低频波段的旋臂内年轻脉冲星；
(b) 深化对星际色散与散射物质分布的认知，尤其针对银河系内区；
(c) 捕获意外发现，获取独特天体（例如拥有黑洞伴星的脉冲星与短周期双星脉冲星）；
(d) 在高频波段开展瞬变射电天空巡天。
模拟结果表明，本次巡天预计将总计探测到200颗脉冲星，其中约半数为首次探测到的新脉冲星。
