Extended Data Fig. 5: Comparison of energy E and actions Jϕ,R,z for the Phoenix stream and all Milky Way globular clusters.

Extended Data Fig. 5

a–c, The actions are computed with AGAMA52 in the best-fit Milky Way potential44. Pal 5 (red circles) is the closest in energy and actions to the Phoenix stream (green star), suggesting a possible association. There is also a potential relation in this space to NGC 5053 (blue circles), another globular cluster. All other global clusters are shown in black.
