On the properties of the massive binary black hole merger GW170729
Katerina Chatziioannou, Roberto Cotesta, Sudarshan Ghonge +53
We present a detailed investigation into the properties of GW170729, the gravitational wave with the most massive and distant source confirmed to date. We employ an extensive set o…
All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO O2 data
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1130
We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast-spinning neutron stars with an asymmetry around their rotation axis,…
Surrogate model for an aligned-spin effective one body waveform model of binary neutron star inspirals using Gaussian process regression
Benjamin D. Lackey, Michael Pürrer, Andrea Taracchini +1
Fast and accurate waveform models are necessary for measuring the properties of inspiraling binary neutron star systems such as GW170817. We present a frequency-domain surrogate ve…
Enriching the Symphony of Gravitational Waves from Binary Black Holes by Tuning Higher Harmonics
Roberto Cotesta, Alessandra Buonanno, Alejandro Bohé +3
For the first time, we construct an inspiral-merger-ringdown waveform model within the effective-one-body formalism for spinning, nonprecessing binary black holes that includes gra…

Dynamical Tides in General Relativity: Effective Action and Effective-One-Body Hamiltonian
Jan Steinhoff, Tanja Hinderer, Alessandra Buonanno +1
Tidal effects have an important impact on the late inspiral of compact binary systems containing neutron stars. Most current models of tidal deformations of neutron stars assume th…
Validating the effective-one-body model of spinning, precessing binary black holes against numerical relativity
Stanislav Babak, Andrea Taracchini, Alessandra Buonanno
In Ref. [1], the properties of the first gravitational wave detected by LIGO, GW150914, were measured by employing an effective-one-body (EOB) model of precessing binary black hole…
Effects of neutron-star dynamic tides on gravitational waveforms within the effective-one-body approach
Tanja Hinderer, Andrea Taracchini, Francois Foucart +11
Extracting the unique information on ultradense nuclear matter from the gravitational waves emitted by merging, neutron-star binaries requires robust theoretical models of the sign…
Numerical relativity reaching into post-Newtonian territory: a compact-object binary simulation spanning 350 gravitational-wave cycles

We present the first numerical-relativity simulation of a compact-object binary whose gravitational waveform is long enough to cover the entire frequency band of advanced gravitati…
Small mass plunging into a Kerr black hole: Anatomy of the inspiral-merger-ringdown waveforms
Andrea Taracchini, Alessandra Buonanno, Gaurav Khanna +1
We numerically solve the Teukolsky equation in the time domain to obtain the gravitational-wave emission of a small mass inspiraling and plunging into the equatorial plane of a Ker…

Yi Pan, Alessandra Buonanno, Andrea Taracchini +7
The detection of gravitational waves and the extraction of physical information from them requires the prediction of accurate waveforms to be used in template banks. For that purpo…
