利用Parkes Radio Telescope进行LUNASKA月球切伦科夫观测的现状和策略
Status and Strategies of Current LUNASKA Lunar Cherenkov Observations with the Parkes Radio Telescope
摘要:
LUNASKA(月球UHE中微子天体物理学与平方公里阵列)是一个正在进行的项目,进行月球切伦科夫观测,以开发新一代射电望远镜探测中微子的技术。我们目前的观测活动是利用64米帕克斯射电望远镜,使用一个带宽为1.2-1.5千兆赫的300兆赫多波束接收器。在这里,我们提供了一个概述的各种因素,必须考虑在信号处理这样的实验。我们还简要地描述了我们希望用我们目前的观测来设定的通量极限,包括半人马座A的方向极限。
英文摘要:
LUNASKA (Lunar UHE Neutrino Astrophysics with the Square Kilometre Array) is an ongoing project conducting lunar Cherenkov observations in order to develop techniques for detecting neutrinos with the next generation of radio telescopes. Our current observing campaign is with the 64-metre Parkes radio telescope, using a multibeam receiver with 300 MHz of bandwidth from 1.2-1.5 GHz. Here we provide an overview of the various factors that must be considered in the signal processing for such an experiment. We also briefly describe the flux limits which we expect to set with our current observations, including a directional limit for Centaurus A.
