在天文光谱中搜寻地外智慧信号,包括现有数据

Searching for extraterrestrial intelligence signals in astronomical spectra, including existing data

Ermanno F. Borra

摘要:

这篇文章的主要目的是让天文学家意识到,通过分析标准的天文光谱,包括他们已经采取的光谱,可以对地外文明进行探测。简单性是光谱搜索的突出优点。光谱可以通过简单的眼睛检查或使用傅里叶变换软件的几行代码进行分析。已发表的实验证实的理论表明,通过发送以恒定时间间隔分隔的光脉冲,可以很容易地产生光谱中的周期性信号。虽然这篇文章的一部分,像所有关于搜索ETI的文章一样,是高度推测性的,但基本的物理原理是合理的。特别是,地球上现有的技术可以用来发送具有所需能量的信号,以便在1000光年以外的目标处被探测到。外星智慧生物(ETI)可以利用这些信号让我们意识到它们的存在。对于ETI,该技术还具有这样的优势,即可以在光谱中检测到信号,并搜索强度脉冲,就像目前在地球上进行的那样。

英文摘要:

The main purpose of this article is to make Astronomers aware that Searches for Extraterrestrial Intelligence can be carried out by analyzing standard astronomical spectra, including those they already have taken. Simplicity is the outstanding advantage of a search in spectra. The spectra can be analyzed by simple eye inspection or a few lines of code that uses Fourier transform software. Theory, confirmed by published experiments, shows that periodic signals in spectra can be easily generated by sending light pulses separated by constant time intervals. While part of this article, like all articles on searches for ETI, is highly speculative the basic physics is sound. In particular, technology now available on Earth could be used to send signals having the required energy to be detected at a target located 1000 light years away. Extraterrestrial Intelligence (ETI) could use these signals to make us aware of their existence. For an ETI, the technique would also have the advantage that the signals could be detected both in spectra and searches for intensity pulses like those currently carried out on Earth.
