The search and follow-up observation of electromagnetic (EM) counterparts of gravitational waves (GW) is a current hot topic of GW cosmology. Due to the limitation of the accuracy of the GW observation facility at this stage, we can only get a rough sky-localization region for the GW event, and the typical area of the region is between 200 and 1500 square degrees. Since GW events occur in or near galaxies, limiting the observation target to galaxies can significantly speedup searching for EM counterparts. Therefore, how to efficiently select host galaxy candidates in such a large GW localization region, how to arrange the observation sequence, and how to efficiently identify the GW source from observational data are the problems that need to be solved. International Virtual Observatory Alliance has developed a series of technical standards for data retrieval, interoperability and visualization. Based on the application of VO technologies, we construct the GW follow-up Observation Planning System (GWOPS). It consists of three parts: a pipeline to select host candidates of GW and sort their priorities for follow-up observation, an identification module to find the transient from follow-up observation data, and a visualization module to display GW-related data. GWOPS can rapidly respond to GW events. With GWOPS, the operations such as follow-up observation planning, data storage, data visualization, and transient identification can be efficiently coordinated, which will promote the success searching rate for GWs EM counterparts.

GWOPS:一种用于搜索引力波事件电磁对应物的 VO 技术驱动工具

引力波(GW)的电磁(EM)对应物的搜索和后续观测是当前引力波宇宙学的热门话题。由于现阶段GW观测设施精度的限制,我们只能得到一个粗略的GW事件天空定位区域,该区域的典型面积在200到1500平方度之间。由于 GW 事件发生在星系内或星系附近,因此将观测目标限制在星系内可以显着加快寻找 EM 对应物的速度。因此,如何在如此大的引力波定位区域内高效地选择宿主星系候选者,如何安排观测序列,以及如何从观测数据中高效地识别引力波源是需要解决的问题。国际虚拟天文台联盟针对数据检索、互操作性和可视化制定了一系列技术标准。基于VO技术的应用,我们构建了GW后续观测计划系统(GWOPS)。它由三个部分组成:一个用于选择GW的宿主候选并对其进行后续观测优先级排序的管道,一个从后续观测数据中找到瞬态的识别模块,以及一个显示GW相关数据的可视化模块。GWOPS 可以快速响应 GW 事件。GWOPS可以有效地协调后续观测规划、数据存储、数据可视化和瞬态识别等操作,这将提高GWs EM对口的搜索成功率。基于VO技术的应用,我们构建了GW后续观测计划系统(GWOPS)。它由三个部分组成:一个用于选择GW的宿主候选并对其进行后续观察优先级排序的管道,一个从后续观察数据中找到瞬态的识别模块,以及一个显示GW相关数据的可视化模块。GWOPS 可以快速响应 GW 事件。GWOPS可以有效地协调后续观测规划、数据存储、数据可视化和瞬态识别等操作,这将提高GWs EM对口的搜索成功率。基于VO技术的应用,我们构建了GW后续观测计划系统(GWOPS)。它由三个部分组成:一个用于选择GW的宿主候选并对其进行后续观测优先级排序的管道,一个从后续观测数据中找到瞬态的识别模块,以及一个显示GW相关数据的可视化模块。GWOPS 可以快速响应 GW 事件。GWOPS可以有效地协调后续观测规划、数据存储、数据可视化和瞬态识别等操作,这将提高GWs EM对口的搜索成功率。识别模块从后续观测数据中发现瞬变,以及显示GW相关数据的可视化模块。GWOPS 可以快速响应 GW 事件。GWOPS可以有效地协调后续观测规划、数据存储、数据可视化和瞬态识别等操作,这将提高GWs EM对口的搜索成功率。识别模块从后续观测数据中发现瞬变,以及显示GW相关数据的可视化模块。GWOPS 可以快速响应 GW 事件。GWOPS可以有效地协调后续观测规划、数据存储、数据可视化和瞬态识别等操作,这将提高GWs EM对口的搜索成功率。
