The binary separation at this stage is approximately a=100 R_g (gravitational radius), and the orbital speed is of order v/c=0.1. We argue that at this stage, the binary will be producing bright electromagnetic (EM) radiation via gas bound to the individual BHs. Both BHs will have their own photospheres in X-ray and possibly also in optical bands. Relativistic Doppler modulations and lensing effects will inevitably imprint periodic variability in the EM light-curve, tracking the phase of the orbital motion, and serving as a template for the GW inspiral waveform. Advanced localization of the source by LISA weeks to months prior to merger will enable a measurement of this EM chirp by wide-field X-ray or optical instruments. A comparison of the phases of the GW and EM chirp signals will help break degeneracies between system parameters, and probe a fractional difference difference Delta v in the propagation speed of photons and gravitons as low as Delta v/c = O(10^-17).","lang":"eng"}],"external_id":{"arxiv":["1705.06765"]},"article_processing_charge":"No","scopus_import":"1","month":"07","quality_controlled":"1","doi":"10.1103/physrevd.96.023004","publication_identifier":{"issn":["2470-0010","2470-0029"]},"publication":"Physical Review D","year":"2017","oa":1,"oa_version":"Preprint","citation":{"ieee":"Z.
