Resolved stellar populations in and around the Galaxy in the era of Euclid

This workshop aims to bring together astronomers within the Euclid Consortium to kickstart the scientific exploration of the mission's first major data release (DR1). Timed to occur shortly after DR1 becomes available in mid/late-2025, the event focuses on the vast legacy science potential of Euclid's data. While designed to map dark matter and dark energy, Euclid's deep, wide-field, high spatial resolution imaging will provide an unprecedented view on resolved stellar populations in the Milky Way, its satellites, star clusters, Magellanic Clouds, and other nearby galaxies. The workshop will serve as a crucial, interactive platform for experts to share knowledge, coordinate efforts, and establish the initial science projects that will capitalize on the one-year proprietary access to this unique dataset.

The overarching goal is to maximize the scientific return from Euclid by fostering collaboration and developing a clear strategy for analysis. Participants will work to define a roadmap for tackling key scientific questions, such as detecting faint stellar streams, discovering and follow-up of ultra-faint dwarf galaxies, and probing the history of the Milky Way (and its satellites) through globular clusters. The workshop is designed to be highly interactive, with the specific objectives of consolidating teams, sharing analysis code and techniques, and organizing task forces for essential follow-up observations. By bringing together the community the workshop will ensure that the wealth of data from Euclid is effectively harnessed in a time-critical manner and pave the way to many exciting discoveries in resolved stellar populations in and around the Milky Way.
