Parkes observations for project P512 semester 2007APRS_03

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\n(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\n(d) to survey the transient radio sky at high frequencies.我们提议利用新型甲醇多波束接收机（Methanol Multibeam receiver）沿银道面（Galactic Plane）开展脉冲星巡天续作，以发掘此前在低频巡天中被筛选排除的脉冲星。本巡天的科学目标如下： (a) 发现螺旋臂中于低频段被遮蔽的年轻脉冲星； (b) 增进我们对星际色散与散射介质分布的认知，尤其是银河系内区； (c) 偶遇并斩获特殊天体（例如拥有黑洞伴星的脉冲星及短周期双星脉冲星）； (d) 开展高频暂现射电天空巡天。
