GWecc.jl computes Pulsar Timing Array signals due to gravitational waves from eccentric supermassive binary sources. This is a partial Julia rewrite of the C++ package GWecc.

This code is based on Susobhanan et al. 2020 and Susobhanan 2022. If you use this code in your work please cite the original articles

See citation.bib for bibtex entries.

Installation

I suggest installing this package in a new conda environment to avoid conflicts with existing package installations. I also suggest installing enterprise-pulsar via conda before installing GWecc.jl to make sure that tempo2, which is a dependency of enterprise-pulsar, is installed properly.

```

conda create -n gwecc python=3.10 conda activate gwecc conda install -c conda-forge enterprise-pulsar conda install -c conda-forge julia ```

GWecc.jl can be installed by typing the following in a Julia REPL:

```

julia julia> import Pkg julia> Pkg.add(url="https://github.com/abhisrkckl/GWecc.jl.git") julia> exit() ```

The Python wrapper can be installed by typing

```

pip install git+https://github.com/abhisrkckl/GWecc.jl.git ```

Note that the Julia package should be installed before installing the Python interface.

Usage

GWecc.jl is intended to be used used together with ENTERPRISE package to search for eccentric supermassive binary sources and with libstempo to simulate such sources. Examples of such usage is given in the examples/ directory (work in progress...).

abstract: >-
  GWecc.jl computes Pulsar Timing Array signals due to
  gravitational waves from eccentric supermassive binary
  sources. The underlying orbital dynamics incorporates
  leading order orbital decay due to gravitational radiation
  reaction and third post-Newtonian-order advance of
  periapsis. This package is designed to be used with the
  ENTERPRISE package for gravitational wave analysis using
  Pulsar Timing Array data.
