PyTGR (PyTesting General Relativity)

This code collects a variety of gravitational waveform templates in modified gravity, and can be easily called by PyCBC based on the PyCBC waveform plugin. This enables any subsequent gravitational wave data analysis with PyCBC, such as Bayesian parameter estimation with a non-GR waveform template, using matched-filtering to search for non-GR gravitational wave signals , etc.

Currently, the models supported are:

• Massive graviton
• Gravitational wave birefringence [1,2]
• dipole radiation
• FTA (flexible theory agnostic)

Constribution are welcome!

Usage

First install PyCBC by

pip install pycbc

Then install the birefringence waveforms for gravitational waves by

python setup.py install

More information should in principle be in the documentation and examples, which are under construction.
