摘要

本文报告了由学生主导的地外智能(SETI)搜索(也称为技术信号)的结果,该搜索以银河系平面为目标,是刘易斯教育研究中心(LCER)与喷气推进实验室合作的金石苹果谷射电望远镜(GAVRT)的一部分。刘易斯教育研究中心(LCER)的相关学生提交针对银河系特定区域的光谱数据分析报告,识别可能来自智能信号源的干扰、噪音和候选信号。GAVRT-SETI的搜索是以这样一个假设为指导的:从天空中的一个固定位置发出的窄带无线电信号(1.5赫兹),在多个观测时段内出现,不太可能是由仪器噪声或自然信号源引起的。因此,我们在报告的数据中搜索了同一天空区域内不同观测时段出现的类似信号。没有发现此类信号。不过,我们对候选信号频率分布的分析表明,至少有百分之几的候选信号与低水平射频干扰有关。

The Goldstone Apple Valley Radio Telescope (GAVRT) Search for Extra Terrestrial Intelligence (SETI)
This paper reports the results from a student-led Search for Extraterrestrial Intelligence (SETI), also known as technosignatures, targeting the plane of the Milky Way as a part of the Goldstone Apple Valley Radio Telescope (GAVRT) collaboration between the Lewis Center for Educational Research (LCER) and the Jet Propulsion Laboratory. Students associated with LCER submit analytic reports of spectral data targeting specific regions of the Milky Way, identifying interference, noise, and Candidate signals potentially originating from intelligent sources. GAVRT-SETI's search is guided by the assumption that a narrow-band radio signal (<1.5 Hz) from a fixed location in the sky, occurring across multiple observation periods, is unlikely to be caused by instrument noise or by a natural source. Thus, we searched the reported data for similar signals occurring during different observation periods within the same region of sky. No such signals were found. However, our analysis of the frequency distribution of Candidates suggests that at least a few percent of the Candidates are associated with low-level radio-frequency interference.

期刊介绍: The Publications of the Astronomical Society of the Pacific (PASP), the technical journal of the Astronomical Society of the Pacific (ASP), has been published regularly since 1889, and is an integral part of the ASP''s mission to advance the science of astronomy and disseminate astronomical information. The journal provides an outlet for astronomical results of a scientific nature and serves to keep readers in touch with current astronomical research. It contains refereed research and instrumentation articles, invited and contributed reviews, tutorials, and dissertation summaries.
