Unraveling the MACHO Mystery II

9727520古尔德俄亥俄州立大学的安德鲁·古尔德博士将进行几项研究，旨在解决与微透镜现象有关的难题。微透镜现象用于寻找暗物质（有时被称为macos），暗物质可能构成我们银河系的大部分质量。他的主要研究领域是：(1)对在银河系凸起处发现的微透镜事件进行后续观察和分析，以更好地了解它们的性质；(2)试图更好地确定星系凸起的微透镜事件是否可以用圆盘质量函数或球体质量函数更好地解释，从而获得关于透镜性质的重要线索；(3)研究在银河系内部的微透镜搜索中发现的~ 10000颗RR天琴座型恒星，可以了解到银河系球体与棒状结构之间的关系。了解银河系凸起中有条纹和无条纹成分之间的关系，可能会为解决这个方向的微透镜谜题提供重要线索。

9727520 Gould Dr. Andrew Gould of Ohio State University will carry out several lines of research aimed at resolving puzzles associated with the microlensing phenomenon used to search for dark matter (sometimes referred to as MACHOs) that may comprise a majority of the mass of our Milky Way galaxy. His principal areas of investigation are (1) Follow-up observations and analysis of microlensing events detected in the bulge of the Galaxy to better understand their nature; (2) Attempt to better determine whether microlensing events in the bulge of the Galaxy are better explained by a disk or spheroid mass function, and thus obtain important clues as to the nature of the lenses; and (3) Study what can be learned about the relation between the spheroid and the bar of the Galaxy from the ~10,000 RR Lyrae type stars that will be found in microlensing searches in the inner Galaxy. Understanding the relation between the barred and the unbarred components of the Galactic bulge may yield important clues to a solution of the microlensing puzzles in this direction.
