Hybrid waveforms for precessing quasi-circular binary systems
Joan Llobera-Querol, Sascha Husa, Maria de Lluc Planas
The demand for long and accurate gravitational waveforms is increasing as we prepare for the next generation of detectors and seek to improve current waveform models. However, nume…
First eccentric inspiral-merger-ringdown analysis of neutron star-black hole mergers
Maria de Lluc Planas, Sascha Husa, Antoni Ramos-Buades +1
The gravitational wave event GW200105 was the first confident neutron star-black hole (NSBH) merger identified by the LIGO-Virgo-KAGRA collaboration. A recent analysis by Morras et…
Eccentric or circular? A reanalysis of binary black hole gravitational wave events for orbital eccentricity signatures
Maria de Lluc Planas, Antoni Ramos-Buades, Cecilio GarcÃa-Quirós +3
We present a reanalysis of 17 gravitational-wave events detected with Advanced LIGO and Advanced Virgo in their first three observing runs, using the new IMRPhenomTEHM model -- a p…
Time-domain phenomenological multipolar waveforms for aligned-spin binary black holes in elliptical orbits
Maria de Lluc Planas, Antoni Ramos-Buades, Cecilio GarcÃa-Quirós +3
We introduce IMRPhenomTEHM, a new phenomenological time-domain model for eccentric aligned-spin binary black holes. Building upon the accurate quasi-circular IMRPhenomTHM model, IM…
