pytgr package

Submodules

pytgr.birefringence module

pytgr.birefringence.gen_waveform(**kwds)[source]

pytgr.birefringence.integrand(redshift)[source]: The integrand: (1.0 + z)^parity_beta / sqrt(Omega_m (1+z)^3 + Omega_Lambda)

pytgr.dipole module

pytgr.dipole.genwav(dipole_b=0.0, **kwds)[source]

pytgr.dipole.genwav_seobnrv4_rom(dipole_b=0.0, **kwds)[source]

pytgr.fta module

pytgr.fta.gen_waveform(**kwds)[source]

Generate waveform with FTA (flexible theory agnostic) correction. Described in https://arxiv.org/pdf/1811.00364.pdf “Tests of General Relativity with GW170817”

Parameters

kwds: dict: Only support dchi2 atm.

Returns

hp: pycbc.types.FrequencySeries: Plus polarization time series
hc: pycbc.types.FrequencySeries: Cross polarization time series

pytgr.massivegraviton module

pytgr.massivegraviton.gen_waveform(**kwds)[source]

Generate waveform with massive graviton correction, assuming no effects are introduced to binary dynamics. Refer to https://journals.aps.org/prd/pdf/10.1103/PhysRevD.57.2061 “Bounding the mass of the graviton using gravitational-wave observations of inspiralling compact binaries” by Clifford Will for more details

Parameters

kwds: dict: The parameters defining the waveform to generator. In particular,

one should provide “lambda_g”, the Compton wavelength for massive graviton, and ‘baseapprox’, the based GR waveform, on top of which correction from massive graviton will be added.

Returns

hp: pycbc.types.FrequencySeries: Plus polarization time series
hc: pycbc.types.FrequencySeries: Cross polarization time series

Module contents

pytgr.length_in_time(**kwds)[source]
