Query: PyROQ: a Python-based Reduced Order Quadrature Building Code for Fast
  Gravitational Wave Inference   The next generation of gravitational-wave observatories will reach low
frequency limits on the orders of a few Hz, thus enabling the detection of
gravitational wave signals of very long duration. The run time of standard
parameter estimation techniques with these long waveforms can be months or even
years, making it impractical with existing Bayesian inference pipelines.
Reduced order modeling and reduced order quadrature integration rule have
recently been exploited as promising techniques that can greatly reduce
parameter estimation computational costs. We describe a Python-based reduced
order quadrature building code, PyROQ, which builds the reduced order
quadrature data needed to accelerate parameter estimation of gravitational
waves. We present the first bases for the IMRPhenomXPHM waveform model of
binary-black-hole coalescences, including subdominant harmonic modes and
precessing spins effects. Furthermore, the code infrastructure makes it
directly applicable to the gravitational wave inference for space-borne
detectors such as the Laser Interferometer Space Antenna (LISA).
