WitrynaThis test checks that IMRPhenomXPHM hasn't changed. It does this by generating two PhenomXPHM waveforms and computing their difference (according to their amplitude and phases) and compares them to pre-computed values. these pre-computed values were computed using the following line: Witryna• Samples of IMRPhenomXPHM model gathered by running MultiNest using the original relative binning algorithm • We target events with either strong precession effects or large contributions from subdominant modes: • Large in-plane spins • Large total mass • Small mass ratio q = m2/m1 < 1 • Five events (4 injected events, 1 real event)

Witryna30 mar 2024 · While IMRPhenomXPHM is a precessing spin model, all remaining models are restricted to aligned-spin systems. The published LVC analysis Abbott and others ( 2024b ) , however, implies that GW190814 is a low-spinning system with effective inspiral spin χ e f f = − 0.001 + 0.060 − 0.061 and an effective precession … WitrynaWe present IMRPhenomXPHM, a phenomenological frequency-domain model for the gravitational-wave signal emitted by quasicircular precessing binary black holes, which incorporates multipoles beyond the dominant quadrupole in the precessing frame. The model is a precessing extension of IMRPhenomXHM, [C. García-Quirós et al., Phys. … highest investment banking analyst salary
