论文摘要

在非洲大陆,南非拥有世界一流的天文学设施,用于先进的射电天文学研究。随着南非平方公里阵列项目的出现(SA SKA),非洲的六个国家(SA SKA合作伙伴国家)加入了南非,为非洲非常长的基线干涉法(VLBI)网络(AVN)做出了贡献。每个AVN国家都将很快拥有一个单人射电望远镜,该望远镜将成为AVN,欧洲VLBI网络和全球VLBI网络的一部分。 SKA和AVN将使南半球的敏感性非常高。在当前的AVN网络中,中非地区的覆盖范围存在差距。这项工作分析了如果要建造新天线或将旧电信设施转换为中部非洲六个国家的射电望远镜,即喀麦隆,加蓬,刚果,刚果,赤道几内亚,乍得,乍得,中部非洲共和国的每个国家。这项工作还讨论了在非洲该地区拥有无线电干涉仪的一些经济和技能转移影响。

In the African continent, South Africa has world-class astronomical facilities for advanced radio astronomy research. With the advent of the Square Kilometre Array project in South Africa (SA SKA), six countries in Africa (SA SKA partner countries) have joined South Africa to contribute towards the African Very Long Baseline Interferometry (VLBI) Networks (AVN). Each of the AVN countries will soon have a single-dish radio telescope that will be part of the AVN, the European VLBI Network, and the global VLBI network. The SKA and the AVN will enable very high sensitivity VLBI in the southern hemisphere. In the current AVN network, there is a gap in coverage in the central African region. This work analyses the scientific impact if new antennas were to be built or old telecommunication facilities were to be converted to radio telescopes in each of the six countries in central Africa i.e. Cameroon, Gabon, Congo, Equatorial Guinea, Chad, Central African Republic. The work also discusses some economical and skills transfer impacts of having a radio interferometer in this area of Africa.
