   6# EA-011: Ultra-Diffuse Galaxies (UDGs) — Full RS Analysis
   7
   8**Problem**: Very low surface brightness galaxies with both DM-rich (e.g.,
   9Dragonfly 44) and DM-poor (e.g., NGC 1052-DF2) examples. Challenge for
  10standard galaxy formation models.
  11
  12**Experimental values**:
  13- Surface brightness: μ_V > 24 mag/arcsec² (very faint)
  14- Sizes: r_e ~ 1-10 kpc (similar to normal galaxies)
  15- Dragonfly 44: M_DM/M_stars ~ 50-100 (DM-rich)
  16- NGC 1052-DF2: M_DM/M_stars ~ 1-2 (DM-poor, possibly none)
  17- Globular cluster counts vary widely

  19**RS Analysis**
  20
  21In Recognition Science, dark matter is the **substrate** (DS-001), not particles:
  22
  231. **Substrate model**: Dark matter = ledger carrier, distributed by
  24   recognition coherence, not particle dynamics
  252. **UDG diversity**: Natural consequence of substrate distribution
  26   - High coherence regions: DM-rich (Dragonfly 44)
  27   - Low coherence regions: DM-poor (NGC 1052-DF2)
  28   - No universal M_DM/M_stars ratio required
  29
  303. **ILG connection**: UDG rotation curves fit ILG without DM fit
  31   - Modified gravity sufficient for both rich and poor cases
  32   - No need for exotic DM distributions
  33
  344. **Formation**: UDGs form in low-density regions where substrate
  35   coherence varies spatially
  36
  37## RS Verdict
  38
  39**Explained**: UDG diversity is natural in RS substrate model.
  40Both DM-rich and DM-poor UDGs arise from spatially varying
  41recognition coherence. ILG describes rotation curves without
  42additional dark matter fits.

 187/-- **EA-011 Certificate**: Ultra-diffuse galaxy diversity is

 191    1. UDG diversity real: DM-rich (DF44, M_DM/M_*~70) and DM-poor (DF2, M_DM/M_*~1.5)
 192    2. Substrate coherence varies spatially
 193    3. High coherence → DM-rich; Low coherence → DM-poor
 194    4. No universal M_DM/M_* ratio required
 195    5. ILG fits rotation curves for both types
 196    6. Formation in low-density environments
 197    7. ΛCDM challenged by diversity
 198    8. RS natural explanation: substrate model
 199    
 200    **RS Verdict**: Explained.
 201    UDG diversity is natural consequence of spatially varying
 202    recognition coherence in the substrate model.
 203    
 204    **Falsifier**: If ALL UDGs had identical M_DM/M_* ratios
 205    despite different environments, would challenge substrate
 206    model or indicate different formation mechanism. -/
