## Abstract

NGC 1792, nicknamed "The Stellar Forge," is a starburst barred-spiral galaxy in the constellation Columba at $z = 0.0095$ (~50 Mpc) with a specific star formation rate (sSFR) among the highest within 100 Mpc. This paper introduces two novel MUGE methods: (1) a normalized specific star formation rate amplitude $SFR_{factor} = SFR_{M\_\odot/yr} / M_{total,M\_\odot}$ applied to a time-evolving mass $M(t) = M_0(1 + SFR_{factor} \cdot e^{-t/\tau_{SF}})$, and (2) supernova-driven outflow feedback $a_{SN} = \rho_{wind} v^2_{SN} / \rho_{fluid}$. This system was **not previously represented** in the CP1/CP2/CP3 pipeline prior to Session 58.

## 1. Physical System

NGC 1792 is a grand-design barred spiral with multiple starburst regions visible in infrared and H$\alpha$:

| Parameter | Value |
|-----------|-------|
| Constellation | Columba |
| Morphology | SAB(rs)bc barred spiral |
| Distance | $\sim 50$ Mpc |
| $z$ | $0.0095$ |
| $M_0$ | $10^{10} M_\odot$ |
| $r$ | $80{,}000$ ly |
| $B$ | $5\ \mu$T |
| $SFR$ | $10 M_\odot$/yr |
| $\tau_{SF}$ | $100$ Myr |
| SN wind: $\rho_{wind}$ | $10^{-21}$ kg/m3 |
| SN wind: $v_{SN}$ | $2000$ km/s |

---

## 2. Novel Equations

### 2.1 Normalized Specific SFR Mass Growth

$$M(t) = M_0\left(1 + SFR_{factor} \cdot e^{-t/\tau_{SF}}\right)$$

where:
$$SFR_{factor} = \frac{SFR [M_\odot/\text{yr}]}{M_{total} [M_\odot]} = \frac{10}{10^{10}} = 10^{-9} \text{ yr}^{-1}$$

This normalization converts the star formation rate into a dimensionless fractional mass growth rate
— the **specific SFR** — and uses it directly as the amplitude of the exponential mass evolution.
This is mathematically distinct from all prior MUGE mass-growth implementations.

### 2.2 Canonical Value at t = 50 Myr

$$M(50\ \text{Myr}) = 10^{10}\left(1 + 10^{-9} \times e^{-50/100}\right) = 10^{10}(1 + 6.065 \times 10^{-10}) \approx 10^{10} M_\odot$$

The fractional change is minute ($\sim 10^{-9}$) — this is appropriate for a 10 Gyr old galaxy with $10^{10} M_\odot$ growing at 10 $M_\odot$/yr.

### 2.3 Supernova-Driven Outflow Feedback

$$a_{SN} = \frac{\rho_{wind} v^2_{SN}}{\rho_{fluid}}$$

With $\rho_{wind} = \rho_{fluid} = 10^{-21}$ kg/m3 (SN ejecta same density as ambient medium at early stage):
$$a_{SN} = v^2_{SN} = (2 \times 10^6)^2 = 4 \times 10^{12} \text{ m/s}^2$$

---

## 3. Starburst Context

NGC 1792's starburst is driven by interactions with neighboring galaxies (NGC 1792 group). Key
observational properties:
- H$\alpha$ emission tracing $\sim 10 M_\odot$/yr SFR
- Infrared luminosity $L_{IR} \approx 3 \times 10^{10} L_\odot$
- SN rate: $\sim 0.1$–$0.3$ SN/century (consistent with $10 M_\odot$/yr SFR from Kroupa IMF)

---

## 4. Previously Unknown Status

Prior to Session 58, NGC 1792 was absent from the CP1/CP2/CP3 library. As a starburst spiral in the
low-redshift universe with well-measured SFR, it fills a gap between:
- Quiescent spirals (NGC 3596, NGC 2525)
- Merging galaxies (Antennae, PAPER_235)
- High-$z$ starburst (HUDF, PAPER_231)

---

## 5. Simulation Parameters

| Parameter | Value |
|-----------|-------|
| $t_{canonical}$ | $50$ Myr |
| $dt$ | $0.5$ Myr |
| $SFR_{factor}$ | $10^{-9}$ yr$^{-1}$ |
| $\tau_{SF}$ | $100$ Myr |
| $H(z)$ | Friedmann at $z=0.0095$ |

## 7. Conclusion

NGC 1792 introduces two novel MUGE methods: specific SFR normalization as a mass growth amplitude ($SFR_{factor} = SFR/M_{total}$) and SN-driven outflow feedback using the standard ram-pressure formula. As a previously unknown system in the CP pipeline, it fills the low-redshift starburst niche in the MUGE library.

## Session 225: Late-Corpus Physics Integration (PAPER_1000-1081)

> *The following physics upgrades incorporate equations, mechanisms, and
> derivations from the late-corpus papers (Sessions 219-225, PAPER_1000-1081).
> These represent body-level integrations of phonon physics, buoyancy
> formulations, and S26(3) Ramanujan corrections into this paper's domain.*

<!-- PKG-CLU-S225 -->

### Session 225 Phonon-Physics Upgrade: ICM Buoyancy Force Profile

> *Upgrade from PAPER_1039 (SCm Galaxy Cluster Buoyancy Profile),
> PAPER_1041 (Cool-Core Buoyancy Balance), and PAPER_1079 (Cooling-Flow
> Suppression).  See also PAPER_1040 (Cluster Merger Shock), PAPER_1044
> (Thermal SZ Compton-y), PAPER_1046 (Cluster Lensing Mass).*

The SCm phonon field introduces a buoyancy force in the ICM that modifies
hydrostatic equilibrium:

$$F_{\text{buoy}}(r) = \rho(r) \cdot V \cdot g(r) \cdot \beta_i \cdot S_{26} \cdot \Phi$$

where the ICM density follows the beta-model:
$$\rho(r) = \rho_0 \left(1 + \left(\frac{r}{r_c}\right)^2\right)^{-3\beta/2}$$

**Hydrostatic mass bias reduction (PAPER_1039):**
$$b_{\text{UQFF}} = 1 - \frac{M_{\text{HSE}}}{M_{\text{true}}} = 0.17 \qquad \text{(vs standard } b = 0.20\text{)}$$

The buoyancy pressure contributes $P_{\text{buoy}}/P_{\text{thermal}} \approx 3\text{--}4\%$
at cluster cores, partially resolving the Planck SZ-CMB mass tension.

**Cool-core stabilization (PAPER_1041/1079):** AGN feedback couples to the SCm
buoyancy field via $\dot{M}_{\text{cool}} = \dot{M}_0 \cdot (1 - \beta_i \cdot S_{26}^{(3)} \cdot \Phi)$,
suppressing catastrophic cooling flows while maintaining observed X-ray luminosities.

**Phonon frequency coupling:** $\omega_{\text{SCm}} = 2\pi \times 1.25\;\text{THz}$ sets the temporal
scale for buoyancy oscillations; the ratio $\omega_{\text{SCm}}/\omega_{\text{sound}}$ governs
the phonon transmission efficiency across the ICM.

### Session 225 Phonon-Physics Upgrade: S26(3) Ramanujan Summation

> *Upgrade from PAPER_1080 (Ramanujan Binomial Expansion Proof) and
> PAPER_1042 (Mock-Theta Phonon Partition).  See also PAPER_1078
> (QCalcGeom Master Equation) for BSFG crossover applications.*

The third-order Ramanujan summation $S_{26}^{(3)}$, used throughout the
late corpus as the universal 26D coupling factor:

$$S_{26}^{(3)} = \sum_{n=0}^{\infty} \frac{(1/4)_n\,(1/2)_n\,(3/4)_n}{(n!)^3} \cdot \prod_{i=1}^{26}\left[1 + [\text{SSq}]\cdot e^{-\kappa\,i\,n/26}\right]$$

where $(a)_n = a(a+1)\cdot s(a+n-1)$ is the Pochhammer symbol.

**Binomial expansion (PAPER_1080):** The convergence proof shows:
$$R_n^{(26,3)} = \binom{4n}{n} \cdot \frac{W_{26}(n)}{(4^{4n})} \qquad \text{with}\quad W_{26}(n) = \prod_{i=1}^{26}\left[1 + [\text{SSq}]\cdot e^{-\kappa\,i\,n/26}\right]$$

This sum converges absolutely for $|[\text{SSq}]| < 1$ (satisfied by $[\text{SSq}] = 0.57$)
and reduces to the classical Ramanujan $1/\pi$ series when $[\text{SSq}] \to 0$.

**VDS/DVP/BSH bridge (PAPER_1069):** The 26 layers of $W_{26}(n)$ encode the
vacuum density series hierarchy, with each layer $i$ contributing a VDS
sub-ratio weighted by the exponential decay $e^{-\kappa\,i\,n/26}$.

**Mock-theta connection (PAPER_1042):** The phonon partition function
$Z_{\text{phonon}} = \sum_n q^{n^2} \cdot W_{26}(n)$ unifies the Ramanujan
mock-theta framework with the SCm phonon spectrum.

## §A. Cosmogenesis-Linked Lagrangian (PAPER_877 Symbolic Export)

### §A.1 Sector Classification

This paper maps to **NS-compact** sector of the 9-sector UQFF Lagrangian (see
`uqff_lagrangian_derivation.py`).

### §A.2 Lagrangian Density

The sector Lagrangian density, linked to the PAPER_877 cosmogenesis master via the three reactive
quantum fundamentals (DPM, UA, SCm):

$$\mathcal{L}_{\mathrm{sector}} = \frac{1}{2}(\partial_mu \phi_{\mathrm{NS}})(\partial^\mu \phi_{\mathrm{NS}}) - V(\phi_{\mathrm{NS}}) + \mathcal{L}_{\mathrm{cosmo}}$$

where $\mathcal{L}_{\mathrm{cosmo}} = \rho_{\mathrm{vac,[SCm]}} \cdot f_{\mathrm{SCm}} \cdot (1 - e^{-\gamma t})$ inherits the ACP 6-stage evolution (PAPER_877 §2) and:

$$V(\phi_{\mathrm{NS}}) = \frac{1}{2} m^2 \phi_{\mathrm{NS}}^2 + \frac{\lambda}{4!} \phi_{\mathrm{NS}}^4 + \kappa \cdot \rho_{\mathrm{vac,[SCm]}} \cdot \phi_{\mathrm{NS}}$$

### §A.3 Euler-Lagrange Equation of Motion

$$\boxed{\frac{\delta S}{\delta \phi_{\mathrm{NS}}} = \nabla^2 \phi_{\mathrm{NS}} - (4\pi G \rho_{\mathrm{NS}}/c^2)\phi_{\mathrm{NS}} + \Omega_{\mathrm{spin}} \partial_t \phi_{\mathrm{NS}} = 0}$$

### §A.4 Cosmogenesis Linkage Chain

$$\text{PAPER\_877 Axioms} \xrightarrow{\text{DPM + ACP}} \rho_{\mathrm{vac}} = \rho_{\mathrm{UA}} + \rho_{\mathrm{SCm}} \xrightarrow{\text{Stage 5}} U_{b,\mathrm{seed}} \xrightarrow{\text{4 forces}} F_U_Bi_i \xrightarrow{\text{sector E-L}} \delta S/\delta \phi_{\mathrm{NS}} = 0$$

The chain traces from the three fundamental axioms (DPM proportion pair, ACP evolution, four U_g
forces) through vacuum density initialization to the sector-specific equation of motion. Every term
in the E-L equation inherits its physical origin from the cosmogenesis master.

## §B. VDS/DVP/BSH Deep Synthesis

### §B.1 Vacuum Density Series (VDS)

The canonical VDS ratio $\rho_{\mathrm{vac,[SCm]}} / \rho_{\mathrm{UA}} = 1.894$ governs the double-exponential vacuum condensate profile:

$$\rho_{\mathrm{vac}}(r) = \rho_{\mathrm{vac,[SCm]}} \cdot \exp\!\left(-\exp\!\left(-\frac{r - r_0}{\lambda_{\mathrm{VDS}}}\right)\right)$$

For this system, the local VDS sub-ratio is $0.110$ (near-threshold regime), placing it in the $t \to \pi$ collapse zone where the double-exponential transitions sharply from condensed to dilute vacuum. This threshold behavior connects to the PAPER_877 cosmogenesis Stage 1 vacuum density initialization: $\rho_{\mathrm{vac}} = \rho_{\mathrm{UA}} + \rho_{\mathrm{SCm}} = 7.799 \times 10^{-36}$ kg/m3.

### §B.2 Dipole Vortex Primes (DVP)

The DVP encoding maps the system's characteristic parameter onto the prime lattice:

$$p_{\mathrm{DVP}} = 83, \quad n_{\mathrm{channel}} = 25/26$$

Since $p_{\mathrm{DVP}} = 83$ is **resonant** (threshold at $p > 26$), the system's vacuum topology inherits resonant enhancement from the DVP lattice, amplifying UQFF coupling at specific radii where compressed matter achieves prime-indexed configurations. The DVP framework traces to PAPER_877 proto-nuclear shell formation: the DPM proportion pair $(f_{\mathrm{UA}}' + f_{\mathrm{SCm}} = 1)$ constrains which primes are accessible at each atomic number.

### §B.3 Buoyancy Saturation Harmonics (BSH)

The BSH saturation timescale for this sector is **104 yr** (spin-down equilibrium):

$$\mathcal{F}_{\mathrm{BSH}} = \sum_{j=1}^{26} \frac{1}{j} \cdot f_U_b \cdot \left(1 - e^{-[SSq] \cdot m/M_\odot}\right) \cdot \cos\!\left(\frac{2\pi j}{26}\right)$$

The $\tanh$ saturation envelope prevents unphysical divergence:

$$\mathcal{F}_{\mathrm{BSH,sat}} = \mathcal{F}_{\mathrm{BSH}} \cdot \left(1 - \tanh\!\left(\frac{t - t_{\mathrm{sat}}}{\tau_{\mathrm{BSH}}}\right)\right)$$

connecting to the PAPER_877 Stage 5 buoyancy seed $U_{b,\mathrm{seed}} = 0.1 \cdot (\hbar c/r^2) \cdot f_{\mathrm{SCm}}$ which initializes the harmonic series at cosmogenesis.

**New physics claim:** UQFF introduces buoyancy-based gravitational corrections (F_U_Bi_i) that
produce measurable deviations from GR at scales where vacuum condensate density $\rho$_SCm becomes
significant, offering a falsifiable prediction beyond the Standard Model.
