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.

银河系盘是地球、太阳系和一千亿颗恒星的家园，是黑暗天空中一个雄伟的天体。然而，经过一个世纪的详细研究，人们对它的许多最基本的性质，如它的规模、质量、化学结构以及不同时期形成的恒星的数量和性质，仍知之甚少。乔·博维的研究利用了大量新数据集的力量，结合了复杂的统计技术，对银河系的结构和历史进行了明确的测量。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。
