A. G. Abac et al 2026 The Astrophysical Journal Letters 1007 .
Caption: Figure 8.
Corner plots of the modified-gravity parameters Ξ0 (left) and cM (right), and the merger rate parameter γ, obtained with the dark siren method and assuming the FULLPOP-4.0 mass model. Vertical dashed lines in the abscissa indicate the GR limit of the respective modified-gravity parameters. The contours indicate the 68.3% and 90% CR.
