Simulate a galaxy.

The QAG velocity law, live. Drag the sliders — the cyan curve is the full QAG prediction, the gray curve is Newton alone with the same baryons.

\[v(r) = \sqrt{\Upsilon_\star \cdot v_{bar}^2(r) + v_{\infty}^2 \cdot \left(1 - e^{-r/r_{aff}}\right)}\]
v(10 kpc): –
Newton-only at 10 kpc: –
Affinity boost: –

Toy model for intuition: exponential-disk baryons + the QAG affinity term with locked constants (a₀ = 1.2047×10⁻¹⁰, KASB = 0.013829). Real fits use the SPARC dataset through the full optimization engine — that's the Researcher Tier.
