The next decade of black hole spectroscopy

Miriam Cabero, Julian Westerweck, Collin D. Capano +3

Gravitational wave observations of the ringdown of the remnant black hole in a binary black hole coalescence provide a unique opportunity of confronting the black hole no-hair theo…

Open data from the first and second observing runs of Advanced LIGO and Advanced Virgo

The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1245

Advanced LIGO and Advanced Virgo are actively monitoring the sky and collecting gravitational-wave strain data with sufficient sensitivity to detect signals routinely. In this pape…

The Relativistic Geoid: Gravity Potential and Relativistic Effects

Dennis Philipp, Eva Hackmann, Claus Lämmerzahl +1

The Earth's geoid is one of the most essential and fundamental concepts to provide a gravity field-related height reference in geodesy and associated sciences. To keep up with the…

On average properties of inhomogeneous fluids in general relativity III: general fluid cosmologies

Thomas Buchert, Pierre Mourier, Xavier Roy

We investigate effective equations governing the volume expansion of spatially averaged portions of inhomogeneous cosmologies in spacetimes filled with an arbitrary fluid. This wor…

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…

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…
