gwent 0.2.0

Gravitational Wave Detector Design Toolkit.

gwent

Gravitational Wave dEtector desigN Toolkit.

Generates strain sensitivity curves and Waterfall plots for various gravitational wave detector designs.

• Free software: MIT license

• Documentation: https://gwent.readthedocs.io.

Features

Calculates the sensitivity curves for various designs of pulsar timing arrays, space-based detectors, and ground-based detectors. This includes:

• NANOGrav

• SKA

• LISA

• aLIGO

• Voyager

• and more!

Calculates the strain from coalescing black hole binaries. It contains functionality for different source descriptions:

• Slowly-evolving sources, ie. BHBs early in their inspiral where they appear to not change in frequency.

• Rapidly-evolving sources, ie. BHBs in the final stages of coalescence.

  • Uses a fully Pythonic implementation of the phenomenological model IMRPhenomD to accurately represent the inspiral, merger, and ringdown of the BHB.

Calculates the matched-filtered signal-to-noise ratio (SNR) to help assess the detectability of any BHB source configuration by any represented gravitational wave detector.

• Includes robust plotting methods to represent these SNRs.

Getting Started

gwent is available on the Python Package Inventory, so the preferred method to install gwent is to install it with pip, as it will always install the most recent stable release.

$ pip install gwent

To install pygwinc, a GitLab hosted package necessary to fully utilize gwent, run this command in your terminal:

$ pip install git+https://git.ligo.org/gwinc/pygwinc.git@65396ee42e851ab7189618cabe1c12081b5d982e#egg=pygwinc

Credits

This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.
