Abstract

GW250114, with a signal-to-noise ratio of ∼80, enables the most precise single-event tests of strong-field gravity to date: setting the tightest constraints on deviations from general relativity, delivering the cleanest ringdown measurement yet, and placing stringent bounds on compact object structure. The one thing it withholds is Love: no tidal deformability is detected, with a 90% upper limit of $\tilde{\Lambda} < 34.8$, fully consistent with the Kerr prediction of vanishing tidal deformability.
