摘要:
SETILive是一个网络项目,转发来自SETI研究所艾伦望远镜阵列(ATA)的无线电信号,供志愿者分析。它包含了一个大型档案,其中有超过7500个测量觇标的150多万次观测,包括开普勒望远镜和其他来源发现的系外行星的方向。它还支持用于信号收集和分类的各种工具。直到最近,它支持来自ATA的信号的实时馈送以及反馈回路,可以中断时间表并重复观察足够多的观众注册的有趣信号。不幸的是,自2014年10月12日起,实时馈送已停止。我们希望,考虑到搜索主题的重要性、全世界对该主题的兴趣以及已经收集的数据的价值,该项目将继续下去。在本文中,我们提出了存储在SETILive存档的数据的统计分析结果,使用Radon变换和专门构造的过滤器选择单光束,潜在的信号ET起源。我们还将根据信号的信噪比使用蒙特卡罗模拟估计信号的统计显著性,并在档案中选择28个强信号,共1072个统计显著信号。
英文摘要:
SETILive is a web project forwarding radio signals from SETI Institute's Allen Telescope Array (ATA) for the analysis of volunteers. It contains a large archive with more than 1.5 millions observations for more than 7.5 thousands observation targets, including directions to exoplanets discovered by telescope Kepler and other sources. It also supports various tools for signal collection and classification. Till recent time it supported live feeds of signals from ATA together with a feedback loop, a possibility to interrupt the schedule and repeat the observation of an interesting signal registered by sufficiently many viewers. Unfortunately, since 12-Oct-2014 the live feeds have been discontinued. We hope that the project will persist, taking into account the importance of the search subject, the worldwide interest to the topic and the value of already collected data. In this paper we present the results of statistical analysis of data stored in SETILive archive, using Radon transform and specially constructed filter for selection of single beams, potential signals of ET origination. We will also estimate statistical significance of signals depending on their signal-to-noise ratio using Monte Carlo simulation and select 28 strong signals and totally 1072 statistically significant signals in the archive.
