Modeling the postmerger gravitational wave signal and extracting binary properties from future binary neutron star detections
Ka Wa Tsang, Tim Dietrich, Chris Van Den Broeck
Gravitational wave astronomy has established its role in measuring the equation of state governing cold supranuclear matter. To date and in the near future, gravitational wave meas…
A morphology-independent search for gravitational wave echoes in data from the first and second observing runs of Advanced LIGO and Advanced Virgo
Ka Wa Tsang, Archisman Ghosh, Anuradha Samajdar +4
Gravitational wave echoes have been proposed as a smoking-gun signature of exotic compact objects with near-horizon structure. Recently there have been observational claims that ec…
GW150914 peak frequency: a novel consistency test of strong-field General Relativity
Gregorio Carullo, Gunnar Riemenschneider, Ka Wa Tsang +2
We introduce a novel test of General Relativity in the strong-field regime of a binary black hole coalescence. Combining information coming from Numerical Relativity simulations of…
A standard siren measurement of the Hubble constant from GW170817 without the electromagnetic counterpart
M. Fishbach, R. Gray, I. Magaña Hernandez +316
We perform a statistical standard siren analysis of GW170817. Our analysis does not utilize knowledge of NGC 4993 as the unique host galaxy of the optical counterpart to GW170817.…
Time-domain effective-one-body gravitational waveforms for coalescing compact binaries with nonprecessing spins, tides and self-spin effects
Alessandro Nagar, Sebastiano Bernuzzi, Walter Del Pozzo +21
We present TEOBResumS, a new effective-one-body (EOB) waveform model for nonprecessing (spin-aligned) and tidally interacting compact binaries.Spin-orbit and spin-spin effects are…
Empirical tests of the black hole no-hair conjecture using gravitational-wave observations
Gregorio Carullo, Laura van der Schaaf, Lionel London +10
We show that second-generation gravitational-wave detectors at their design sensitivity will allow us to directly probe the ringdown phase of binary black hole coalescences. This o…
