Time domain phenomenological model of gravitational wave subdominant harmonics for quasi-circular non-precessing binary black hole coalescences
Héctor Estellés, Sascha Husa, Marta Colleoni +5
In this work we present an extension of the time domain phenomenological model IMRPhenomT for gravitational wave signals from binary black hole coalescences to include subdominant…
Initial Data and Eccentricity Reduction Toolkit for Binary Black Hole Numerical Relativity Waveforms
Sarah Habib, Antoni Ramos-Buades, E. A. Huerta +3
The production of numerical relativity waveforms that describe quasicircular binary black hole mergers requires high-quality initial data, and an algorithm to iteratively reduce re…
Towards the routine use of subdominant harmonics in gravitational-wave inference: re-analysis of GW190412 with generation X waveform models
Marta Colleoni, Maite Mateu-Lucena, Héctor Estellés +5
We re-analyse the gravitational-wave event GW190412 with state-of-the-art phenomenological waveform models. This event, which has been associated with a black hole merger, is inter…
Bayesian inference for compact binary coalescences with BILBY: Validation and application to the first LIGO--Virgo gravitational-wave transient catalogue
I. M. Romero-Shaw, C. Talbot, S. Biscoveanu +56
Gravitational waves provide a unique tool for observational astronomy. While the first LIGO--Virgo catalogue of gravitational-wave transients (GWTC-1) contains eleven signals from…
Impact of eccentricity on the gravitational wave searches for binary black holes: High mass case
Antoni Ramos-Buades, Shubhanshu Tiwari, Maria Haney +1
The possible formation of stellar-mass binary black holes through dynamical interactions in dense stellar environments predicts the existence of binaries with non-negligible eccent…
IMRPhenomTP: A phenomenological time domain model for dominant quadrupole gravitational wave signal of coalescing binary black holes
Héctor Estellés, Antoni Ramos-Buades, Sascha Husa +4
In this work we present IMRPhenomTP, a time domain phenomenological model for the dominant , modes of coalescing black hole binary systems and its extension to describ…
Computationally efficient models for the dominant and sub-dominant harmonic modes of precessing binary black holes
Geraint Pratten, Cecilio García-Quirós, Marta Colleoni +8
We present IMRPhenomXPHM, a phenomenological frequency-domain model for the gravitational-wave signal emitted by quasi-circular precessing binary black holes, which incorporates mu…
Validity of common modelling approximations for precessing binary black holes with higher-order modes
Antoni Ramos-Buades, Patricia Schmidt, Geraint Pratten +1
The current paradigm for constructing waveforms from precessing compact binaries is to first construct a waveform in a non-inertial, co-precessing binary source frame followed by a…
Setting the cornerstone for the IMRPhenomX family of models for gravitational waves from compact binaries: The dominant harmonic for non-precessing quasi-circular black holes
Geraint Pratten, Sascha Husa, Cecilio Garcia-Quiros +4
In this paper we present IMRPhenomXAS, a thorough overhaul of the IMRPhenomD [1,2] waveform model, which describes the dominant spherical harmonic mode of non-pr…
IMRPhenomXHM: A multi-mode frequency-domain model for the gravitational wave signal from non-precessing black-hole binaries
Cecilio García-Quirós, Marta Colleoni, Sascha Husa +5
We present the IMRPhenomXHM frequency domain phenomenological waveform model for the inspiral, merger and ringdown of quasi-circular non-precessing black hole binaries. The model e…
