The Milky Way's disk, home to the Earth, Solar System, and a hundred billion stars, is a majestic object in the dark sky. Yet after a century of detailed study, many of its most basic properties such as its scale, mass, chemical structure, and the number and properties of stars formed at different epochs are poorly understood. Jo Bovy'sresearch leverages the power of large new data sets in combination with sophisticated statistical techniques to make definitive measurements of the Milky Way's structure and history. This work provides important new insights into the physics of galaxy formation and dark matter.

银河系的圆盘，地球，太阳系和一千亿颗恒星的家园，在黑暗的天空中是一个雄伟的物体。然而，经过世纪的详细研究，它的许多最基本的性质，如它的规模，质量，化学结构，以及在不同时期形成的恒星的数量和性质仍然知之甚少。Jo Bovy的研究利用大型新数据集的力量，结合复杂的统计技术，对银河系的结构和历史进行明确的测量。这项工作为星系形成和暗物质的物理学提供了重要的新见解。
