Relationships between the angular momentum along z direction Lz vs. eccentricity e for the GC groups. Top panel: in situ GCs associated with the Galactic halo, bulge, or intruders into the bulge in comparison with OCs. Middle panel: GCs from three accretion events, Gaia Sausage, Sequoia, and Sagittarius, compared with in situ GCs and OCs. Bottom panel: GCs from the accretion events Kraken and Gaia Enceladus, compared with in situ GCs and OCs.
