Isotropic-equivalent energy of the Swift/GUANO γ-ray signal at the distance of GW241125 (magenta) compared to the populations of short (orange) and long (blue) GRBs from the Swift data archive. Points with an arrow are for events with only upper-limit constraints on their redshifts; the magenta error bars reflect the GW distance uncertainty under the hypothesis of an association between the Swift/GUANO signal and GW241125. The green line estimates Swift/BAT’s detection threshold as a function of redshift.
