论文摘要
上下文：最稀有的可变性类型之一是重力微透明的现象，这是由于中间的透镜对象而导致背景恒星的瞬时亮度。微覆盖是以银河系（包括行星和黑洞）研究无形或无法检测到的人群的强大工具。目的：我们描述了Microlensing事件候选的第一个Gaia目录，概述其内容并讨论其验证。方法：通过分析2014年至2017年间覆盖34个月的GAIA数据释放3的光曲线，GAIA微透明事件的目录是组成的。结果：我们介绍了363个Gaia微透镜事件并讨论其性质。以前从未报告过90个事件，也没有被其他调查发现。目录的污染评估为0.6-1.7％。
Context: One of the rarest types of variability is the phenomenon of gravitational microlensing, a transient brightening of a background star due to an intervening lensing object. Microlensing is a powerful tool in studying the invisible or otherwise undetectable populations in the Milky Way, including planets and black holes. Aims: We describe the first Gaia catalogue of microlensing event candidates, give an overview of its content and discuss its validation. Methods: The catalogue of Gaia microlensing events is composed by analysing the light curves of around 2 billion sources of Gaia Data Release 3 from all over the sky covering 34 months between 2014 and 2017. Results: We present 363 Gaia microlensing events and discuss their properties. Ninety events were never reported before and were not discovered by other surveys. The contamination of the catalogue is assessed to 0.6-1.7%.
