Technical Note XLV
Equations and coefficients — reference sheet
All quantities in SI units: mass \(M\) in kg, distances \(d, R, r\) in metres. Universal parameters: \(\lambda = 12.696\), \(c = 0.163\), \(\ell_{floor} = 3.00\) kpc \(= 9.26\times10^{19}\) m.
1. Model definitions (exact, not fitted)
Wave mass and total mass
Enclosed wave-mass profile
Wave density (exponential kernel)
Rotation velocity
2. Three linear relations (log–log, 7 cosmic levels)
Each relation is a straight line in log–log coordinates — i.e. a power law of the form \(\log_{10} y = a\,\log_{10} x + b\). Least-squares fits on the seven representative levels; M is the total mass \((1+\lambda)M_{vis}\). The scatter \(\sigma\) measures how tightly the points lie on each line; it does not affect the linearity.
Relation 1 — Mass vs distance to neighbours \(d\)
Equivalently \(d \propto M^{0.49} \approx \sqrt{M}\). Tightest of the three.
Relation 2 — Mass vs object radius \(R\)
Close to \(M \propto R\) on this broad sample (not \(R^2\)).
Relation 3 — Surface density \(M/R^2\) vs mass \(M\)
A straight line of slope \(-0.74\) — linear in log–log, but with a non-zero slope, so \(M/R^2\) is not constant across the full range (a true cosmic constant would mean slope \(0\)). This relation is also algebraically implied by Relations 1–2, since \(M/R^2\) is built from \(M\) and \(R\). Median over the sample: \(M/R^2 \approx 8.4\ \text{kg/m}^2 \approx 0.84\ \text{g/cm}^2\) (meaningful only within the restricted galaxy-to-cluster regime).
3. Coefficient summary
All three are linear in log–log (\(\log_{10} y = a\,\log_{10} x + b\)); the columns give the prefactor \(10^{b}\) and the slope \(a\).
| Equation | Prefactor | Exponent | Scatter |
|---|---|---|---|
| M vs d | 7.65×10⁻⁴ | +2.05 | 0.63 dex |
| M vs R | 6.03×10²⁰ | +1.05 | 1.49 dex |
| M/R² vs M | 9.89×10³² | −0.74 | 2.71 dex |
| M_wave / M_vis | λ = 12.696 | — | exact |
| M_total / M_vis | 1+λ = 13.696 | — | exact |
Note: the factor \((1+\lambda)\) enters only the prefactors (a constant +1.14 dex vertical shift), never the exponents. The fitted slopes are unchanged whether one plots visible or total mass.
