Thanks for your participation in the GA workshop 2024 in Matsushima!

Understanding the Milky Way and nearby galaxies has made significant progress in recent years due to advancements in observational instruments and data analysis methods. Gaia, for instance, has revealed the three-dimensional chemical and dynamical structure of the Milky Way, as well as traces of mergers with dwarf galaxies. Furthermore, discoveries of dwarf galaxies through projects like HSC and DES, as well as observational constraints on primordial black holes using the microlensing effect, are actively contributing to the observational verification of dark matter models.

To establish more robust scenarios for the formation of the Milky Way and tighter constraints on dark matter models, it is essential to make full use of detailed theoretical predictions based on large-scale simulations and leverage large-scale and high-precision data from next-generation astronomical observations. With the imminent commencement of scientific operations for PFS, it is crucial to share the current status of research in this field, engage in discussions for the next observational survey, and clarify the direction moving forward. This serves as an important step in the process.

In this workshop, our focus will be on the formation history of small-scale structures, with the Milky Way galaxy serving as a representative case, and the verification of dark matter theories based on this history. We aim to connect the latest findings in theoretical and observational studies and engage in discussions regarding future large-scale observational projects. To achieve this goal, we will bring together leading researchers from both domestic and international communities in this field, fostering diverse exchanges of opinions based on the most recent observational data and simulation insights.
