Azimuthal velocity V_ϕ as a function of metallicity: In situ (top) and all accreted (bottom) stellar populations. Black lines show the mean azimuthal velocity values, while blue and red show 5% and 95 − 5% statistics of the velocity distribution. The red vertical solid and dashed lines highlight the boundaries similar to the ones used to identify the Aurora and Splash populations in the MW (Belokurov & Kravtsov 2022). The HESTIA galaxies show a behaviour similar to the MW with a little rotation of the low-[Fe/H] (<  − 1.2…−0.8) stars and a sharp spin-up of the net rotation for more metal-rich stars ([Fe/H] < −0.5).
