Enabling real-time multi-messenger astrophysics discoveries with deep learning
E. A. Huerta, Gabrielle Allen, Igor Andreoni +57
Multi-messenger astrophysics is a fast-growing, interdisciplinary field that combines data, which vary in volume and speed of data processing, from many different instruments that…
Including higher order multipoles in gravitational-wave models for precessing binary black holes
Sebastian Khan, Frank Ohme, Katerina Chatziioannou +1
Estimates of the source parameters of gravitational-wave (GW) events produced by compact binary mergers rely on theoretical models for the GW signal. We present the first frequency…
Testing the"no-hair" nature of binary black holes using the consistency of multipolar gravitational radiation
Tousif Islam, Ajit Kumar Mehta, Abhirup Ghosh +3
Gravitational-wave (GW) observations of binary black holes offer the best probes of the relativistic, strong-field regime of gravity. Gravitational radiation, in the leading order…
Parameter Estimation with a spinning multi-mode waveform model: IMRPhenomHM
Chinmay Kalaghatgi, Mark Hannam, Vivien Raymond
Gravitational waves from compact binary coalescence sources can be decomposed into spherical-harmonic multipoles, the dominant being the quadrupole () modes. The co…
Multi-waveform inference of gravitational waves
Gregory Ashton, Sebastian Khan
Bayesian inference of gravitational wave signals is subject to systematic error due to modelling uncertainty in waveform signal models, coined approximants. A growing collection of…
The Hyperboloidal Numerical Evolution of a Good-Bad-Ugly Wave Equation
Edgar Gasperin, Shalabh Gautam, David Hilditch +1
One method for the numerical treatment of future null-infinity is to decouple coordinates from the tensor basis and choose each in a careful manner. This dual-frame approach is ham…
Black holes in the low mass gap: Implications for gravitational wave observations
Anuradha Gupta, Davide Gerosa, K. G. Arun +3
Binary neutron-star mergers will predominantly produce black-hole remnants of mass , thus populating the putative \emph{low mass gap} between neutron stars and…
Measuring the neutron star equation of state with gravitational waves: the first forty binary neutron star mergers
Francisco Hernandez Vivanco, Rory Smith, Eric Thrane +3
Gravitational waves from binary neutron star coalescences contain rich information about matter at supranuclear densities encoded by the neutron star equation of state. We can meas…
Cosmological Inference using Gravitational Wave Standard Sirens: A Mock Data Challenge
Rachel Gray, Ignacio Magaña Hernandez, Hong Qi +12
The observation of binary neutron star merger GW170817, along with its optical counterpart, provided the first constraint on the Hubble constant using gravitational wave stan…
Two-harmonic approximation for gravitational waveforms from precessing binaries
Stephen Fairhurst, Rhys Green, Charlie Hoy +2
Binary-black-hole orbits precess when the black-hole spins are mis-aligned with the binary's orbital angular momentum. The apparently complicated dynamics can in most cases be desc…
Model comparison from LIGO-Virgo data on GW170817's binary components and consequences for the merger remnant
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1191
GW170817 is the very first observation of gravitational waves originating from the coalescence of two compact objects in the mass range of neutron stars, accompanied by electromagn…
When will we observe binary black holes precessing?
Stephen Fairhurst, Rhys Green, Mark Hannam +1
After eleven gravitational-wave detections from compact-binary mergers, we are yet to observe the striking general-relativistic phenomenon of orbital precession. Measurements of pr…
Upper limits on the amplitude of ultra-high-frequency gravitational waves from graviton-photon mixing
Aldo Ejlli, Damian Ejlli, Adrian Mike Cruise +2
In this work, we present the first experimental upper limits on the presence of stochastic ultra-high-frequency gravitational waves. We exclude gravitational waves in the frequency…

We present results from a semicoherent search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1, using a hidden Markov model (HMM) to track spin wander…
Search for intermediate mass black hole binaries in the first and second observing runs of the Advanced LIGO and Virgo network
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1196
Gravitational wave astronomy has been firmly established with the detection of gravitational waves from the merger of ten stellar mass binary black holes and a neutron star binary.…
Testing the multipole structure and conservative dynamics of compact binaries using gravitational wave observations: The spinning case
Shilpa Kastha, Anuradha Gupta, K. G. Arun +2
In an earlier work [S. Kastha et al., PRD {\bf 98}, 124033 (2018)], we developed the {\it parametrized multipolar gravitational wave phasing formula} to test general relativity, fo…
