Does GW190814 have a hidden third companion lurking nearby?

GW190814 — the merger involving a mysterious 2.6-solar-mass object — was claimed by one group to show signs of a nearby massive third body tugging on the binary. Using 32 seconds of data instead of the 4 seconds used in that claim, no such evidence holds up: the Bayes factor sits at 0.22, firmly against it. More intriguingly, the gravitational-wave signature of a third-body tug and a slightly elliptical orbit are nearly indistinguishable, a degeneracy that likely explains why the earlier analysis got a non-zero result.
