澳大利亚早期对半人马座A的光学和射电观测
Early Australian Optical and Radio Observations of Centaurus A
摘要：
射电源半人马座A及其光学对应物NGC 5128的发现是澳大利亚天文学历史上的重要里程碑。NGC 5128是詹姆斯·邓洛普于1826年8月在悉尼湾定居点以西的帕拉马塔天文台对南方天体进行调查时首次观测到的。该天文台是由英国新南威尔士殖民地的新总督托马斯·布里斯班在几年前建立的。120年后，约翰·博尔顿、戈登·斯坦利和布鲁斯·斯利在悉尼的多佛高地观测站发现了射电源半人马座A，该观测站由CSIRO的无线电物理实验室（澳大利亚望远镜国家设施的前身）运营。本文将描述这一早期的历史工作，并总结了其他放射物理小组到1960年对半人马座A的进一步研究。
英文摘要：
The discoveries of the radio source Centaurus A and its optical counterpart NGC 5128 were important landmarks in the history of Australian astronomy. NGC 5128 was first observed in August 1826 by James Dunlop during a survey of southern objects at the Parramatta Observatory, west of the settlement at Sydney Cove. The observatory had been founded a few years earlier by Thomas Brisbane, the new governor of the British colony of New South Wales. Just over 120 years later, John Bolton, Gordon Stanley and Bruce Slee discovered the radio source Centaurus A at the Dover Heights field station in Sydney, operated by CSIRO's Radiophysics Laboratory (the forerunner of the Australia Telescope National Facility). This paper will describe this early historical work and summarise further studies of Centaurus A by other Radiophysics groups up to 1960.
