Reinterpreting Low Frequency LIGO/Virgo Events as Magnified Stellar-Mass Black Holes at Cosmological Distances

Broadhurst, Tom; Diego, Jose M.; Smoot III, George (NURIS; Energetic Cosmos Laboratory, 2018-02-14)

Gravitational waves can be focussed by the gravity of an intervening galaxy, just like light, thereby magnifying binary merging events in the far Universe. High magnification by galaxies is found to be responsible for the ...
Twin LIGO/Virgo Detections of a Viable Gravitationally-Lensed Black Hole Merger

Broadhurst, Tom; Smoot, George F.; Diego, Jose M. (NURIS; Energetic Cosmos Laboratory, 2019-01-10)

We identify a binary black hole (BBH) merger that appears to be multiply lensed by an intervening galaxy. The LIGO/Virgo events GW170809 and GW170814 have indistinguishable waveforms separated by 5 days, and overlap on the ...
