下一代天文学

Next-generation Astronomy

Ray P. Norris

摘要:

我们研究天文学的方式正在发生根本性的变化。在20年的时间里,大多数天文学家可能永远不会接近尖端的望远镜,这将是更有效地运行在服务模式。他们很少分析数据,因为所有的尖端望远镜都有流水线处理器。天文学家们通常不会竞相观测一个特别有趣的天体,而是组成大型联盟,在精心设计的调查中观测大量的天空,每天产生PB级的数据。我们可以想象,天文生产力将比以往任何时候都高。博士生将使用复杂的工具挖掘庞大的调查数据库,对广阔地区的不同波长数据进行交叉关联,并在开始攻读博士学位后的几个月内得出一线天文学结果。现在用于规划观测的专业知识将用于规划对数据库的入侵。实际上,人们将计划使用虚拟天文台进行观测。在这里,我审视了天文学发现的过程,用水晶球来观察它在未来20年内会如何变化,并确定未来的进一步机会,以及确定我们必须保持警惕的陷阱。

英文摘要:

Fundamental changes are taking place in the way we do astronomy. In twenty years time, it is likely that most astronomers will never go near a cutting-edge telescope, which will be much more efficiently operated in service mode. They will rarely analyse data, since all the leading-edge telescopes will have pipeline processors. And rather than competing to observe a particularly interesting object, astronomers will more commonly group together in large consortia to observe massive chunks of the sky in carefully designed surveys, generating petabytes of data daily. We can imagine that astronomical productivity will be higher than at any previous time. PhD students will mine enormous survey databases using sophisticated tools, cross-correlating different wavelength data over vast areas, and producing front-line astronomy results within months of starting their PhD. The expertise that now goes into planning an observation will instead be devoted to planning a foray into the databases. In effect, people will plan observations to use the Virtual Observatory. Here I examine the process of astronomical discovery, take a crystal ball to see how it might change over the next twenty years, and identify further opportunities for the future, as well as identifying pitfalls against which we must remain vigilant.
