Host galaxy analysis rules out a globular cluster origin for the GRB 230307A kilonova and shows a disk-formed BNS merger with natal kicks can reach the observed offset in only 0.1% of population-synthesis realizations.

Probing the origin of the kilonova candidate GRB 230307A: analysis of host galaxy and offset
Host galaxy analysis rules out a globular cluster origin for the GRB 230307A kilonova and shows a disk-formed BNS merger with natal kicks can reach the observed offset in only 0.1% of population-synthesis realizations.
