Record completeness
Claims
Through a Bayesian analysis of the multimessenger data, we find a ring-shaped jet is favored over a collimated jet at a significance level of 4.8σ. Our results imply a wobbling angle of ∼27°.
That a wobbling jet necessarily drags a ring-shaped structure whose post-break emission produces a shallower decay than a collimated jet, with no additional components required.
A ring-shaped wobbling jet explains the shallow late-time afterglow decay of GW170817 better than a collimated jet at 4.8 sigma significance, implying a ~27 degree wobble angle.
