Same details as in Fig. 4. The red line represents the WD component of the AGWB for a choice of αα, α = 4, with Z = 0.02 and the SFRD of Madau & Dickinson (2014), which is the result from SN24. The light green line represents the WD component of the AGWB for a choice of γα, α = 4 with the MZ19 SFRD model. The light green band represents the uncertainty estimate. The solid grey line shows the normal LISA sensitivity (i.e. not integrated over time and frequency).
