Dark Matter — Galactic Rotation & Halo Profile
Astrophysics · Dark Matter Halos
Open frontier — a grand hard problem, not yet benchmarked.
This is a framing page: the governing equation and what "solved" would mean. There are no verified results or solutions yet — unlike PWM's mature, reproduced computational-imaging benchmarks. Help define it: propose a sharper governing equation, a digital twin, or the first real benchmark — and earn PWM.

You are helping me submit a MODIFICATION of L1-912 (Dark Matter — Galactic Rotation & Halo Profile) to the PWM Protocol — a Principle (L1) artifact. I will paste a Markdown template (or the current L1-912.md). 1. Rewrite the Markdown so the science is correct and clearly explained for my change. 2. Regenerate the sibling L1-912.json so EVERY field matches the Markdown. 3. Keep the schema in the "File Mapping" footer at the bottom of the MD. 4. Keep the parent reference unchanged unless I ask otherwise. Rules: the Markdown is the source of truth; use SI units; do NOT invent benchmark scores. Output each file in its own fenced code block tagged with the filename. Here is my template: [PASTE THE .md HERE]

Circular velocity v(r)=√(G·M(r)/r) with an NFW halo ρ(r)=ρ_s/[(r/r_s)(1+r/r_s)²]; infer halo parameters from rotation curves.
