Image Details
Caption: Figure 1.
Mosaic of HST/F160W image cutouts (HST/F814W for GRB 050709; JWST/F150W for GRB 230307A) of each host galaxy in our sample. The red circles indicate the approximate location of the transients, with the exception of GRB 230307A being at ∼30″ offset outside the scope of the cutout. The red circles are the same pixel size relative to the pixel scale of each image. The localization uncertainties are not used for the circle radii as they are too small and would obscure the local environment.
