Compact Binary Waveforms¶

Compact binary coalescences are the sources which have produced all of the gravitational wave detections to the end of 2023. Minke provides a way of producing waveforms from the various models which are supported by the lalsimulation library.

Binary Black Holes¶

IMRPhenomPv2¶

IMRPhenomPv2 is a precessing, spinning black hole model.

import minke
import astropy.units as u

from minke.models.cbc import IMRPhenomPv2
from minke.detector import AdvancedLIGOHanford

model = IMRPhenomPv2()

parameters = {"mass_ratio": 0.7, "total_mass": 100*u.solMass, "luminosity_distance": 10*u.megaparsec}

data = model.time_domain(parameters)

data = model.time_domain(mass_ratio=0.7, total_mass=100*u.solMass)

f = data['plus'].plot()
f.savefig("waveform.png")

SEOBNRv3¶

import minke
import astropy.units as u

from minke.models.cbc import SEOBNRv3
from minke.detector import AdvancedLIGOHanford

model = SEOBNRv3()

parameters = {"mass_ratio": 0.7, "total_mass": 100*u.solMass, "luminosity_distance": 10*u.megaparsec}

data = model.time_domain(parameters)

data = model.time_domain(mass_ratio=0.7, total_mass=100*u.solMass)

f = data['plus'].plot()
f.savefig("waveform.png")
