dual jets in binary black hole mergers, the simulations of Palenzuela et al. also have strong implications for gravitational wave astrophysics. The electromagnetic waves produced according to this scenario should be detectable, as they present a very clear energy profi le. During inspiral, the dual jets lead to a particular electromagnetic struc-ture, lasting several days and with energies proportional to the magnetic field times the orbital velocity squared. Such emission remains roughly constant over most of the inspiral, as the orbital velocity varies slowly. When the binary merges, a strong isotropic burst of radiation is emitted and the dual jets transition to a Blandford-Znajek jet with its own associated electromagnetic structure. If such a counterpart is observed, it would provide information on the location of the event in the sky. Such an electromagnetic observation could then be used in gravita-tional wave observations to break degenera-cies and measure other astrophysical param-eters more accurately, such as the Hubble constant ( 12) or the dark energy equation of state ( 13), or to test deviations from general relativity ( 14)
