Context
N25: Prediction
The $T^2$ fiber increases the effective shadow radius by $2.91%$ compared to Schwarzschild (V.T220). $τ$-value: $r_ sh = 5.25\,GM/c^2$. Experiment: ngEHT (next-generation EHT). Timeline: 2029–2033.
Derivation Context
- Shadow diameter: $θ_τ = 40.85\,μas$.
- EHT observation: $42 ± 3\,μas$.
- Deviation: $0.4σ$.
- QNM ratio: $ι_τ^-1 ≈ 2.930$.
- Modulation periods: $4.66$ d (outer $S^1$), $1.59$ d (inner $S^1$).
The shadow prediction lies comfortably within the EHT error bar. The $T^2$ correction brings $τ$ $1.15\,μas$ closer to the central value than pure GR.
