## Abstract

NGC 2525 is a barred spiral galaxy at $z = 0.0162$ ($\sim 65$ Mpc) hosting Type Ia supernova SN 2018gv. This paper introduces the only **negative** acceleration term in the entire MUGE system catalogue: the supernova ejecta mass-loss term $g_{SN}(t) = -(G M_{SN}(t))/r^2$ where $M_{SN}(t) = M_{SN0} e^{-t/\tau_{SN}}$ is the declining ejecta mass as it disperses. As the SN ejecta leaves the system, its gravitational contribution decreases — yielding a net negative correction to the total gravitational field. All other systems in the MUGE catalogue use exclusively positive correction terms.

## 1. Physical System

| Parameter | Value |
|-----------|-------|
| Galaxy | NGC 2525, barred spiral, Puppis |
| Distance | $\sim 65$ Mpc |
| $z$ | $0.0162$ |
| $M_{galaxy}$ | $10^{10} M_\odot$ |
| Central BH | $M_{BH} = 2.25 \times 10^7 M_\odot$ |
| $r_{BH}$ | $1$ AU = $1.496 \times 10^{11}$ m |
| SN type | Type Ia (SN 2018gv) |
| $M_{SN0}$ | $1.4 M_\odot$ (Chandrasekhar mass) |
| $\tau_{SN}$ | $1$ yr |

---

## 2. The Negative Mass-Loss Term (Uniquely Novel)

### 2.1 Definition

$$g_{SN}(t) = -\frac{G M_{SN0} e^{-t/\tau_{SN}}}{r^2}$$

At $t = 0$: $g_{SN}(0) = -G M_{SN0}/r^2$ (full Chandrasekhar mass contribution, negative).
At $t \to \infty$: $g_{SN} \to 0$ (ejecta fully dispersed, no contribution).

### 2.2 Physical Basis

For a stellar mass gravitational source, the sign convention in MUGE is that all terms add to the net field. The SN ejecta, however, represents mass **leaving** the system. As it disperses to large radii, it no longer contributes to the local gravitational field at $r_{galaxy}$. The differential equation governing the effective field is:

$$\frac{dg_{SN}}{dt} = +\frac{G M_{SN0}}{\tau_{SN} r^2} e^{-t/\tau_{SN}} > 0$$

i.e., the (negative) correction becomes less negative over time — consistent with dispersal.

### 2.3 Magnitude

At galactic $r_{galaxy} = 30{,}000$ ly:
$$|g_{SN}| \approx \frac{6.674 \times 10^{-11} \times 2.785 \times 10^{30}}{(2.84 \times 10^{20})^2} \approx 2.3 \times 10^{-33} \text{ m/s}^2$$

This is $\sim 18$ orders of magnitude below the dominant BH term — physically negligible at galactic scales but mathematically significant as the sole negative MUGE term.

---

## 3. Friedmann H(z) Correction

$$H(z) = H_0\sqrt{\Omega_m(1+z)^3 + \Omega_Lambda}$$

At $z = 0.0162$:
$$H(z) \approx H_0\sqrt{0.3 \times 1.0487 + 0.7} = H_0 \times 1.0035 \approx 2.275 \times 10^{-18} \text{ s}^{-1}$$

---

## 4. Central BH Contribution

The AGN/BH near the galactic centre at $r_{BH} = 1$ AU:
$$a_{BH} = \frac{GM_{BH}}{r_{BH}^2} = \frac{6.674 \times 10^{-11} \times 2.25 \times 10^7 \times 1.989 \times 10^{30}}{(1.496 \times 10^{11})^2} \approx 1.34 \times 10^6 \text{ m/s}^2$$

---

## 5. Canonical Complete System

$$g_{NGC2525} = a_{grav} + a_{Ug} + a_{\Lambda} + a_{EM} + a_{q} + a_{f} + a_{osc} + a_{DM} + g_{SN} + a_{BH}$$

Only $g_{SN}$ is negative; all other terms positive.

---

## 6. Simulation Parameters

| Parameter | Value |
|-----------|-------|
| $r_{galaxy}$ | $30{,}000$ ly |
| $t_{canonical}$ | $0.5$ yr (SN peak) |
| $M_{SN0}$ | $1.4 M_\odot$ |
| $\tau_{SN}$ | $1$ yr |
| $B$ | $1\ \mu$T |

## 8. Conclusion

The negative SN mass-loss term $g_{SN}(t) = -(GM_{SN0}/r^2)e^{-t/\tau_{SN}}$ is a uniquely rare mathematical discovery within the MUGE catalogue: it is the first and only negative acceleration term across all 19 documents in the grok_{share\_8d951e12}.txt corpus and across the full CP1/CP2/CP3 library. Its physical motivation — dispersing ejecta leaves the gravitational system — is rigorous and directly observable through light-curve evolution of SN 2018gv.

### Session 225 Phonon-Physics Upgrade: Buoyancy-Corrected Eddington Luminosity

> *Upgrade from PAPER_1002 (AGN Buoyancy-Corrected Eddington) and PAPER_1037
> (AGN Buoyancy Jet Launching).  See also PAPER_1009-1010 for F_U_Bi_i jet
> modulation curves and PAPER_1048 for phonon-corrected M-$\sigma$ relation.*

The SCm vacuum buoyancy partially opposes gravitational radiation pressure,
raising the effective Eddington luminosity:

$$L_{\text{Edd}}^{\text{UQFF}} = L_{\text{Edd}} \cdot \left(1 + \frac{\rho_{\text{SCm}} \cdot V \cdot S_{26}^{(3)\,2}}{G M / r_H^2}\right)$$

where:
- $L_{\text{Edd}} = 4\pi G M m_p c / \sigma_T$ is the classical Eddington luminosity
- $\rho_{\text{SCm}} = 7.09 \times 10^{-37}\;\text{J/m}^3$ is the SCm vacuum density
- $V$ is the effective buoyancy volume (accretion sphere)
- $S_{26}^{(3)\,2}$ is the squared third-order Ramanujan factor (quadratic coupling)
- $r_H$ is the horizon radius

**Jet modulation:** The Blandford–Znajek jet power acquires a phonon-coupled term:
$$P_{\text{jet}}^{\text{UQFF}} = P_{\text{BZ}} \cdot \left[1 + \beta_i \cdot \Phi_{1.25\,\text{THz}} \cdot \left(\frac{B}{B_{\text{crit}}}\right)^2\right]$$

where $\Phi_{1.25\,\text{THz}} = \cos(\omega_{\text{SCm}} \cdot t)$ modulates jet power at the phonon frequency.

**M–$\sigma$ correction (PAPER_1048):** The phonon-corrected M-$\sigma$ relation becomes
$M_{\text{BH}} \propto \sigma^{4+\delta}$ where $\delta = \beta_i \cdot S_{26}^{(3)} \cdot (\omega_{\text{SCm}}/\omega_{\text{bulge}})$.



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

### §A.1 Sector Classification

This paper maps to **SNR-explosion** 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):

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

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:

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

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

$$\boxed{\frac{\delta S}{\delta \phi_{\mathrm{SNR}}} = \partial_t(\rho v) + \nabla P_{\mathrm{SNR}} - \rho_{\mathrm{vac,[SCm]}} g_{\mathrm{Ub}} = 0}$$

### §A.4 Cosmogenesis Linkage Chain

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

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 $0.160$ (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:

$$p_{\mathrm{DVP}} = 73, \quad n_{\mathrm{channel}} = 23/26$$

Since $p_{\mathrm{DVP}} = 73$ 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** (Sedov-Taylor transition):

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

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.

| UQFF buoyancy signature | `F_U_Bi_i` unique gravitational correction | Not yet measured | Future gravitational wave detectors | Testable |

**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.
