Depending on the mass of the black holes, they could have anywhere from a fraction of a second together (for a black hole the mass of a planet or star) to days or even weeks (for a black hole with the mass of a small galaxy or more).
The model also shows where in the universe the binary black holes are, how long ago they merged and the masses of each black hole.
Based on the quasar's redshift, the researchers calculated the mass of the black hole at its center and determined that it is around 800 million times the mass of the sun.

Following the initial discovery, two telescopes in southern Arizona did the heavy lifting in determining the distance and mass of the black hole: the 8.4 - meter Large Binocular Telescope, or LBT, on Mount Graham and the 6.5 - meter Multiple Mirror Telescope, or MMT, on Mount Hopkins.
The unsolved key question about these objects asks: what is the mass of the black hole in these bright objects?
NASA researchers say they successfully tested a new way to measure the mass of black holes.
The trick consisted of thinking of the mass of a black hole not as a constant, as had previously been the case, but as a function that depends on the distance to the center of the black hole.
With the help of lasers, he and colleagues detected the first complex molecules in interstellar space and first measured the mass of the black hole in the center of our galaxy.
The galaxy could continue to grow in the future, but the relationship between the mass of the black hole and that of the stars would remain unusually large.
Now observing the mass of a black hole (at least indirectly) is easy: you measure how fast things orbit around it, just the same as any other massive astronomical object.
In recent findings, studies further revealed that the masses of black holes are tightly correlated with those of their host galaxies.
The mass of each black hole is roughly proportional to the mass of the galaxy itself, and makes up approximately half a percent of the total galaxy mass.
«This fundamentally changes determinations of the masses of black holes
«This galaxy is a rare find — a tiny galaxy that is still building up the mass of its black hole.

The mass of the black hole is somewhat arbitrary — the distorting hole could be a big one far away, or a smaller one close by.
Furthermore, the mass of our black hole ranges on the low end of normal for galaxies of our size.
«We need to continue observing this galaxy to improve our understanding of the orbit, and of the masses of the black holes,» Taylor said.
