GWMemory calculates the nonlinear (Christodoulou) gravitational-wave memory waveform from arbitrary time-domain gravitational-waveforms.
GWMemory is available via conda-forge and pypi
$ uv pip install gwmemory
$ conda install -c conda-forge gwmemory
$ python -m pip install gwmemoryYou can also install from this repository in the usual way:
$ git clone https://github.com/ColmTalbot/gwmemory.git
$ cd gwmemory
$ uv syncUse uv sync --extra full for the optional runtime and test dependencies, and uv sync --extra full --extra docs when building the documentation stack.
Demonstrations of how to calculate memory waveforms can be found in the documentation and in the examples directory.

- Aligned spin waveforms in
lalsimulation, e.g.,IMRPhenomD( Khan et al. (2016), Phys. Rev. D 93, 044007,SEOBNRv4(Bohe et al. (2017), Phys. Rev. D 95, 044028). - Minimal waveform model (Favata (2010), CQG, 27, 8)
- Any surrogate model available in

To use these waveform models, you may need to install extra packages, this should be described if the packages aren't available.
Additionally users can supply any waveform decomposed onto the basis of spin-2 weighted spherical harmonics.
There is basic support for loading numerical relativity waveforms, based on the format of the simulating extreme spacetimes waveform catalog.
