Comparison of the median vertical velocity maps between the different evolutionary phases (see Fig. 3) of the LMC Combined optimal sample. From left to right, Young, BL, AGB, and RGB samples – following a rough sequence in age. We display bins containing three or more stars; otherwise, we display individual stars as a scatter plot. A black line splitting the overdensities (LMC bar and spiral arm) from the underdensities is plotted. The cyan ring is centred on the supershell LMC 4 (α = 5h32m, −66∘40′, Book et al. 2008), with a diameter of 1400 pc (Dopita et al. 1985; Ou et al. 2024). All maps are shown in the LMC in-plane (x′, y′) Cartesian coordinate system. To mimic how the LMC is seen in the sky, the plotted data has both axes inverted.
