arxiv.org/abs/2512.04600 The dynamical memory of tidal stellar streams: Joint inference of the Galactic potential and the progenitor of GD-1 with flow matching
Researchers present a Flow Matching and simulation-based inference framework that jointly infers properties of the GD-1 stream progenitor and the Milky Way potential. Trained on mock streams from the Odisseo N-body code, it recovers fiducial GD-1 parameters with well-calibrated posteriors.
