Two-dimensional maps of the gas density (left-hand panels) and of the temperature (central panels) and the pressure (right-hand panels) on the x-y plane for the M5I24 simulation. The corresponding evolutionary time of each set of panels is reported in the density map, together with the velocity field denoted by the white arrows (all arrows have the same length, so no information on the intensity of the field is reported), and the contours describing the region enclosing the 75% and 95% of the SG mass in red and black, respectively. The cyan points on the temperature map represent newborn stars (age <0.05 Myr).
