One surprise from the results was which galaxies are most likely to offer the first glimpse of supermassive black hole merger.
The detection of a supermassive black hole merger would offer new insights into how massive galaxies and black holes evolve, Mingarelli says.
As to whether astronomers will detect a supermassive black hole merger, «it'll be interesting either way,» Mingarelli says.

«Galaxy mergers are common, and we think there are many galaxies harboring binary supermassive black holes that we should be able to detect,» said Joseph Lazio, one of Taylor's co-authors, also based at JPL.
«The gravitational waves from these supermassive black hole binary mergers are the most powerful in the universe,» says study lead author Chiara Mingarelli, a research fellow at the Center for Computational Astrophysics at the Flatiron Institute in New York City.
The successful technology demonstration paves the way for detecting mergers of supermassive black holes with future space - based observatories
Decades from now new generations of space telescopes could capture the mergers of supermassive black holes and glimpse pulsars spiraling to doom down their maws, or see snapping «cosmic strings,» proton - thin intergalactic defects in spacetime that may have been stretched across the infant universe during an inflationary growth spurt.
The mergers that formed NGC 1316 led to an influx of gas, which fuels an exotic astrophysical object at its centre: a supermassive black hole with a mass roughly 150 million times that of the Sun.
Supermassive black holes like the one in galaxy M87 probably grow not only by feeding on infalling gas and stars but also by mergers of smaller black holes.
Most of the black holes in LIGO's mergers have been middleweights, being heavier than that 20 — solar mass limit but much lighter than the supermassive variety, raising questions about their origins and relationship to the two well - studied populations of black holes.
That's because no one knows whether such supergiants grow from scratch within star - forming regions, or whether, like supermassive black holes and galaxies, they reach their enormous mass through mergers.

«We were looking for orbiting pairs of supermassive black holes, with one offset from the center of a galaxy, as telltale evidence of a previous galaxy merger.
Since most galaxies in the universe are believed to harbor one supermassive black hole at their center, the presence of a binary system is conclusive evidence of a galactic merger.
The galaxy mergers that bring two supermassive black holes close together are considered to be a common process in the universe, so astronomers expect that such binary pairs should be common.
«We believe that the two supermassive black holes in this galaxy will merge,» said Karishma Bansal, a graduate student at UNM, adding that the merger will come at least millions of years in the future.
