引力微透镜的研究进展

Recent Developments in Gravitational Microlensing

Andrew Gould

摘要:

在Bohdan的开创性论文推出引力微透镜领域的21年后,它已经从一种狭隘地专注于寻找暗物质的方法彻底多样化为一种非常通用的天文工具。微透镜现在已经探测到了12颗行星,其中包括几颗其他搜索方法无法探测到的行星。它已经解析了遥远恒星的表面,充当了放大镜来拍摄极其微弱物体的光谱,并揭示了许多令人惊讶的现象。我对这种非凡的技术进行了全面的审视,对它的成功和继续推动它前进的紧张局势给予了同等的重视。

英文摘要:

Twenty-one years after Bohdan's seminal paper launched the field of gravitational microlensing, it has radically diversified from a method narrowly focused on finding dark matter to a very general astronomical tool. Microlensing has now detected 12 planets, including several that are inaccessible by other search methods. It has resolved the surfaces of distant stars, served as a magnifying glass to take spectra of extremely faint objects, and revealed a number of surprising phenomena. I take a sweeping look at this remarkable technique, giving equal weight to its successes and to the tensions that are continuing to propel it forward.
