Title: Compact binary Coalescences: Constraints on waveforms
Abstract: Gravitational-wave detections of compact binary coalescences (CBCs) are reliant on accurate modeling. With upcoming future detectors, our models must improve by orders of magnitude. Exact general relativity applied to compact binary coalescences (CBCs) gives constraints that the waveforms must satisfy. These constraints can then be used as qualitatively new checks on the accuracy of waveform models. In this talk, we see the derivation of these constraints using the Bondi-Metzner-Sachs (BMS) group and its associated balance laws in the context of CBCs. We also see applications of this work in understanding the issue of angular momentum ambiguities for CBCs in general asymptotically flat spacetimes.
