Star formation histories, determined with PROSPECTOR, for the host galaxies of GRBs 211211A and 230307A (from Nugent et al. 2025). Errorbars are given on the SFR estimates at each time step, while the red dashed lines are the constructed histograms that we used to weight the model seeding in time. The populations of both galaxies are dominated by star formation within the last 10 Gyr. This biases the merging WDNS binaries in these galaxies to the WD1-NS2 pathway (see Fig. 2).
