Top panel: 95th percentile of the X-ray and radio emission from a thin radial shell at R₁₀₀ as a function of the cluster mass, for ≥5 × 10¹³ M_⊙ clusters in our simulation at z = 0.05. The horizontal lines show the reference detection threshold for both cases. Large symbols correspond to clusters in which ≥1% of the R₁₀₀ shell can be simultaneously detected in X-ray and in radio. Bottom panel: detection fraction for the R₁₀₀ shell in our clusters at z = 0.05, considering the simultaneous detection in X-ray and radio, as a function of the cluster mass.
