The simulations are run with the <a href="https://github.com/quokka-astro/quokka" target="_blank">Quokka</a> radiation-hydrodynamics code, varying the gas surface density, resolution, and metallicity.</p> <p>Each animation shows three quantities: <strong>gas surface density</strong> (Σ), <strong>hot-phase gas flux surface density</strong> (Σ_hot, T &gt; 10⁶ K), and <strong>cool-phase gas flux surface density</strong> (Σ_cool, T &lt; 2 · 10⁴ K).</p> <h2 id="resolution-comparison--σ--50-mpc">Resolution comparison — Σ₀ = 50 M☉/pc²</h2> <div class="video-grid"> <div> <p><strong>4 pc resolution</strong> Download <a href="attach/sigma50-4pc-SigmaM-SigmaMhot-and-SigmaMcool-sigma50-4pc_tiny.mp4">Tiny</a> · <a href="attach/sigma50-4pc-SigmaM-SigmaMhot-and-SigmaMcool-sigma50-4pc_small.mp4">Small</a> · <a href="attach/sigma50-4pc-SigmaM-SigmaMhot-and-SigmaMcool-sigma50-4pc.mp4">Original</a></p>
