Summary of the probability analyses quantifying the tension between the M21 results and the FLAMINGO lightcones using different scaling relations (LX − T, YSZ − T, or their combination), statistical methods (M21 sky scanning or MCMC), and probability estimators (KDE or projected EVS).
| Relation | M21 (KDE) | M21 (projected EVS) | MCMC (KDE) | MCMC (projected EVS) |
|---|---|---|---|---|
| LX − T | p = 0.021 | p = 0.025 (2.25σ) | p = 0.055 | p = 0.032 (2.14σ) |
| YSZ − T | p < 5.8 × 10−4 | p = 1.8 × 10−10 (6.38σ) | p < 5.8 × 10−4 | p = 2.8 × 10−4 (3.64σ) |
| Joint analysis | – | – | p < 5.8 × 10−4 | p = 1.5 × 10−4 (3.78σ) |
| LX − T (scatter) | p = 0.33 | p = 0.23 (1.20σ) | p < 5.8 × 10−4 | p = 0.085 (1.72σ) |
| YSZ − T (scatter) | p < 5.8 × 10−4 | p = 0.0013 (3.22σ) | 0.0014 | p = 0.0049 (2.82σ) |
| Joint analysis (scatter) | − | p = 0.0012 (3.24σ) | p < 5.8 × 10−4 | p = 0.020 (2.32σ) |
Notes. The p-values denote the probability that a randomly placed observer in a ΛCDM universe would measure an anisotropy equal to or more extreme than that seen in M21, with equivalent (1D) Gaussian significance given in parentheses where applicable. ‘Scatter’ refers to the mock samples with matched M21-level instrumental uncertainties (see Sect. 2.4). Dashes indicate configurations beyond the scope of the probability estimators.
