We study binary mergers in bootstrapped Newtonian gravity, where higher-order couplings are added to the non-relativistic Lagrangian for potential. In this theory, Arnowitt-Deser-Misner (ADM) mass differs from both proper of gravity and general relativity, which affects interpretation astrophysical cosmological events. The aforementioned difference particularly provides important phenomenological constraints emitted matter compactness final object after merger. GW150914 signal theory also shows that LIGO's findings do not violate gap, contrary usual claims. indeed find typical stellar black hole masses can fit data a considerable range values. calculate entropy context, leads generalised area law. Non-linear effects found effectively change only gravitational strength via renormalization Newton's constant case.
