by Robin Chan

Functions:

Name Description
gen_IMRPhenomXAS_NRTidalv3

Generate NRTidalv3 frequency domain waveform following 2311.07456.
gen_IMRPhenomXAS_NRTidalv3_hphc

Generate NRTidalv3 frequency domain waveform with plus and cross polarizations.

gen_IMRPhenomXAS_NRTidalv3(f: Float[Array, ' n_freq'], params: Float[Array, 9], f_ref: float, use_lambda_tildes: bool = True, no_taper: bool = False) -> Complex[Array, ' n_freq'] ¤

Generate NRTidalv3 frequency domain waveform following 2311.07456.

Parameters:

Name Type Description Default
f Array

Frequencies in Hz.

 required
params Array

Array containing both intrinsic and extrinsic variables: theta = [Mchirp, eta, chi1, chi2, lambda1, lambda2, D, tc, phic]:

  • Mchirp: Chirp mass of the system [solar masses]
  • eta: Symmetric mass ratio [between 0.0 and 0.25]
  • chi1: Dimensionless aligned spin of the primary object [between -1 and 1]
  • chi2: Dimensionless aligned spin of the secondary object [between -1 and 1]
  • lambda1: Dimensionless tidal deformability of primary object
  • lambda2: Dimensionless tidal deformability of secondary object
  • D: Luminosity distance to source [Mpc]
  • tc: Time of coalescence. This only appears as an overall linear in f contribution to the phase
  • phic: Phase of coalescence
 required
f_ref float

Reference frequency for the waveform.

 required
use_lambda_tildes bool

Use lambda tilde and delta lambda instead of lambda1 and lambda2. Default is True.

 True
no_taper bool

Whether to disable tapering. Default is False.

 False

Returns:

Name Type Description
h0 Array

Strain.

gen_IMRPhenomXAS_NRTidalv3_hphc(f: Float[Array, ' n_freq'], params: Float[Array, 10], f_ref: float, use_lambda_tildes: bool = True, no_taper: bool = False) -> tuple[Complex[Array, ' n_freq'], Complex[Array, ' n_freq']] ¤

Generate NRTidalv3 frequency domain waveform with plus and cross polarizations.

IMRPhenom denotes the name of the underlying BBH approximant used, before applying tidal corrections.

Parameters:

Name Type Description Default
f Array

Frequencies in Hz.

 required
params Array

Array containing both intrinsic and extrinsic variables: theta = [Mchirp, eta, chi1, chi2, lambda1, lambda2, D, tc, phic, inclination]:

  • Mchirp: Chirp mass of the system [solar masses]
  • eta: Symmetric mass ratio [between 0.0 and 0.25]
  • chi1: Dimensionless aligned spin of the primary object [between -1 and 1]
  • chi2: Dimensionless aligned spin of the secondary object [between -1 and 1]
  • lambda1: Dimensionless tidal deformability of primary object
  • lambda2: Dimensionless tidal deformability of secondary object
  • D: Luminosity distance to source [Mpc]
  • tc: Time of coalescence. This only appears as an overall linear in f contribution to the phase
  • phic: Phase of coalescence
  • inclination: Inclination angle of the binary [between 0 and PI]
 required
f_ref float

Reference frequency for the waveform.

 required
