Volumetric rates as a function of redshift calculated using two different methods: galaxy SMD (ℛ_SMD dashed lines), which is suitable for binary mergers with longer delay times between the star formation and the merger, and SFR density (ℛ_SFR, solid lines), suitable for events strongly linked to star formation such as the collapse of massive stars and binary mergers with shorter delay times between star formation and the merger. The rates are computed for different MW event rates (r_MW), ranging from 10⁻⁶ to 10⁻³ yr⁻¹.
