Top panel: GA reconstruction of the coupling ζ as a function of redshift (red line) using the forecast ELT α data (grey background points), the atomic clocks constraints and the MICROSCOPE bound (both at z = 0) and Euclid forecast constraints with a ζw₀w_aCDM fiducial. Bottom panel: reconstruction of the relative variation in the fine-structure constant Δα/α (red line) along with binned values of the data in one (green point) and two bins (blue points). In both cases the red line corresponds to the GA reconstruction, while the shaded region is the 1σ error.
