Isolated dwarf galaxy simulation performed with GAMER. The projected gas density is annotated with young stars (white dots; age ≤ 2.5 Myr) and recent supernovae (red dots; exploded within the past 2.5 Myr). Gas collapses under self-gravity and cools via metal-line radiation. When the Jeans length becomes unresolved, star particles form stochastically and explode as CCSNe after 10 Myr, injecting 10⁵¹ erg thermal energy and driving blast waves that redistribute gas and regulate star formation. The dark-blue region near (x, y) = (0.7 kpc, −0.8 kpc) marks a recent strong explosion. An animation is available that spans 0–750 Myr with a real-time duration of 47 s.
