Ratio of total Lyα to Hα flux for all the Hα emitters in the FoV of the MUSE data presented in this work, and the data from Richard et al. (2021) in the A2744 cluster. We include a 1/8.7 factor for direct comparison with the Case B (T = 10⁴ K) ratio. The dashed and dotted blue lines show the mean and standard deviation in the field, respectively. We note that the fluxes are not dust-corrected. We show the total flux ratio variation in bins of redshift Δz = 0.1 (pink line), and within Δz = 0.02 around the redshift of A2744-45924, itself included (red filled square) and excluded (empty square). The Lyα/Hα ratio in the environment of A2744-45924 is moderate in comparison with other overdensities in our data, despite the large intrinsic overdensity of Hα emitters (Labbe et al. 2024; Matthee et al. 2025).
