Fundamental Physics Implications for Higher-Curvature Theories from Binary Black Hole Signals in the LIGO-Virgo Catalog GWTC-1

“…We build on these efforts and use the constraints on GR deviations obtained by the LIGO-Virgo collaboration (LVC) [30] to analyze whether these two theories can be constrained with the binary BH events detected during the first two observation runs of the LVC. More specifically, we will consider the binary BH events in the LIGO-Virgo Catalog GWTC-1 GW150914 [31,32], GW151226 [33], GW170104 [34], GW170608 [35] and GW170814 [36] for which the posteriors on theory-independent GR modifications, obtained through a Markov-Chain-Monte-Carlo (MCMC) exploration of the parameter space, have been made public [3,37].

A morphology-independent search for gravitational wave echoes in data from the first and second observing runs of Advanced LIGO and Advanced Virgo

“…That said, we explicitly note that in the case of a black hole resulting from a binary neutron star merger of total mass ∼ 2.7 M [35], we expect the dominant ringdown frequency and hence the central frequency f 0 of the echoes to be above 6000 Hz, i.e. above our prior upper bound, but also much beyond the detectors' frequency reach for plausible energies emitted [36]. Foreground and background analyses with a correspondingly high frequency range are left for future work.…”

Modeling the postmerger gravitational wave signal and extracting binary properties from future binary neutron star detections

“…To date, the advanced GW detectors have only been able to observe the inspiral of the two NSs [39,40] and no postmerger signal has been observed. This nonobservation is caused by the higher emission frequency at which current GW detectors are less sensitive.…”
