A code for simulating gravitational waves and evaluating their detectability.
Project description
# riroriro
Riroriro is a set of Python modules containing functions to simulate the gravitational waveforms of mergers of black holes and/or neutron stars, and calculate several properties of these mergers and waveforms.
The modules “inspiralfuns”, “mergerfirstfuns”, “matchingfuns”, “mergersecondfuns” and “gwexporter”, in that order, can be used to simulate the strain amplitude and frequency of a merger gravitational waveform. The module “snrcalculatorfuns” can compare such a simulated waveform to a detector noise spectrum to calculate a signal-to-noise ratio (SNR) for that signal for that detector. The module “horizondistfuns” calculates the horizon distance of a merger given its waveform, and the module “detectabilityfuns” evaluates the detectability of a merger given its SNR.

Riroriro is one of several Python packages associated with BPASS (Binary Population And Spectral Synthesis), a suite of programs that simulates the evolution of a population of binary and single-star systems from a wide range of initial conditions. Each of these associated packages are named after native animals of New Zealand. The riroriro (Gerygone igata, also known as the grey warbler) is a small bird that can be recognised by its distinctive melodious call but is rarely seen, similarly to how black hole binary mergers are detected by their gravitational wave signals rather than visually.
