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…
Regression methods in waveform modeling: a comparative study
Yoshinta Setyawati, Michael Pürrer, Frank Ohme
Gravitational-wave astronomy of compact binaries relies on theoretical models of the gravitational-wave signal that is emitted as binaries coalesce. These models do not only need t…
Finite tidal effects in GW170817: Observational evidence or model assumptions?
Wolfgang Kastaun, Frank Ohme
After the detection of gravitational waves caused by the coalescence of compact objects in the mass range of neutron stars, GW170817, several studies have searched for an imprint o…
All-sky search for short gravitational-wave bursts in the second Advanced LIGO and Advanced Virgo run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1186
We present the results of a search for short-duration gravitational-wave transients in the data from the second observing run of Advanced LIGO and Advanced Virgo. We search for gra…
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,…
