Fast frequency-domain phenomenological modeling of eccentric aligned-spin binary black holes
Antoni Ramos-Buades, Quentin Henry, Maria Haney
We present the IMRPhenomXE frequency-domain phenomenological waveform model for the dominant mode of inspiral-merger-ringdown non-precessing binary black holes in elliptical orbits…

Eccentric or circular? A reanalysis of binary black hole gravitational wave events for orbital eccentricity signatures
Maria de Lluc Planas, Antoni Ramos-Buades, Cecilio García-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 García-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…
