测试澳大利亚光学望远镜的潜在新地点

Testing Potential New Sites for Optical Telescopes in Australia

Claire E. Hotan, Steven J. Tingay, Karl Glazebrook

摘要:

在未来几年,澳大利亚可能会发现需要建造新的光学望远镜,以继续实施当地方案,为全球勘测项目作出贡献,并为正在建造的新射电望远镜建立当地多波长连接。在这项研究中,我们通过研究遥感气象红外数据来确定澳大利亚各地的预期云层覆盖率,并将这些数据与使用地理信息系统的数字高程模型相结合,从而改进新光学望远镜的可能位置。我们发现,在澳大利亚建造光学望远镜的最佳地点可能是在西澳大利亚西北部的哈默斯利山脉的最高山脉,而北领地的麦克唐纳山脉也可能是合适的。我们相信,在确定的地点,应该可以获得与赛丁泉相似的视宁度值,并且观察时间要长得多。我们希望能找到两倍于现有望远镜观测点的晴朗夜晚。因此,这些地点是今后进行现场测试的主要地点。

英文摘要:

In coming years, Australia may find the need to build new optical telescopes to continue local programmes, contribute to global survey projects, and form a local multi-wavelength connection for the new radio telescopes being built. In this study, we refine possible locations for a new optical telescope by studying remotely sensed meteorological infrared data to ascertain expected cloud coverage rates across Australia, and combine these data with a Digital Elevation Model using a Geographic Information System. We find that the best sites within Australia for building optical telescopes are likely to be on the highest mountains in the Hamersley Range in Northwest Western Australia, while the MacDonnell Ranges in the Northern Territory may also be appropriate. We believe that similar seeing values to Siding Spring should be obtainable and with significantly more observing time at the identified sites. We expect to find twice as many clear nights as at current telescope sites. These sites are thus prime locations for future on-site testing.
