Figure 6. Left panel: frequency scaling for the non-spinning binary s0 of the GW luminosity rescaled of a factor 10−10 (black solid line), of the diffused EM luminosity (red solid line), and of the collimated EM luminosity computed in a polar cap with a semi-opening angle of 5◦ (blue solid line). Note that the diffused EM luminosity has a behavior which is compatible with Ω10/3−8/3 as does as the GW luminosity. The collimated EM luminosity, on the other hand, has a scaling compatible with Ω5/3−6/3. Right panel: the same as in the left panel but reporting only the GW emission and extrapolating back in the past to determine when the collimated and the diffused emissions are comparable. For a binary with 108 M this happens ∼21 days before merger.
