Gas density (left), temperature (middle), and metallicity (right) maps for the Boötes I-like galaxy in the z = 0 plane at five representative times, i.e., t = 3, 13, 20, 25, and 30 Myr. The projected positions of the OB associations are shown on the metallicity maps as gray circles, with sizes proportional to the number of massive stars. The snapshots refer to the galaxy simulated in the adiabatic limit at high resolution.
