Abstract

We run a three-dimensional Galactic chemical evolution (GCE) model to follow the propagation of 53Mn (exclusively produced from type Ia supernovae, SNIa), 60Fe (exclusively produced from core-collapse supernovae, CCSNe), 182Hf (exclusively produced from intermediate mass stars, IMSs), and 244Pu (exclusively produced from neutron star mergers, NSMs). By comparing the pre- dictions from our three-dimensional GCE model to recent detections of 53Mn, 60Fe, and 244Pu on the deep-sea floor, we draw conclusions about their propagation in the interstellar medium.
