利用Lasair从Rubin警报流中开展科学研究
Enabling Science from the Rubin Alert Stream with Lasair
AI总结：
本文介绍了英国LSST暂现源警报社区代理系统Lasair的功能、实现与使用方式，其支持用户构建警报过滤器、共享资源及实时机器通知，且已通过ZTF警报流验证成熟性。
AI中文摘要：
Lasair是维拉·C·鲁宾天文台（Vera C. Rubin Observatory）时空遗产巡天（Legacy Survey of Space and Time, LSST）暂现源警报的英国社区代理系统。本文阐述了该系统的功能、用户实现其科学目标的方式，以及Lasair的实现机制。Lasair为用户提供一套组件工具，用户可借此构建过滤器以筛选出所需的警报。该工具包包含新颖的光变曲线特征、天区背景信息、特殊天体和天区的监视列表、与已知天文源星表的动态交叉匹配，以及来自其他用户和合作项目的分类与标注。这些资源可与其他用户共享、复制和修改。Lasair还可针对过滤后的暂现源警报提供实时的机器间通知。尽管鲁宾天文台尚未建成，Lasair已是一套成熟的系统：它一直在处理并提供来自格式相似的兹威基瞬变设施（Zwicky Transient Facility, ZTF）警报流的数据。
英文摘要：
Lasair is the UK Community Broker for transient alerts from the Legacy Survey of Space and Time (LSST) from the Vera C. Rubin Observatory. We explain the system's capabilities, how users can achieve their scientific goals, and how Lasair is implemented. Lasair offers users a kit of parts that they can use to build filters to concentrate their desired alerts. The kit has novel lightcurve features, sky context, watchlists of special sky objects and regions of the sky, dynamic crossmatching with catalogues of known astronomical sources, and classifications and annotations from other users and partner projects. These resources can be shared with other users, copied, and modified. Lasair offers real-time machine-to-machine notifications of filtered transient alerts. Even though the Rubin Observatory is not yet complete, Lasair is a mature system: it has been processing and serving data from the similarly formatted stream of the Zwicky Transient Facility (ZTF) alerts.
