pagn 1.1.0

Solutions to parametric AGN disk models

pagn

pagn is a Python module for solving the AGN disk models of Sirko & Goodman (2003) and Thompson et al. (2005). It is designed to be simple, transparent, and highly customizable.

Given a set of physical inputs, pagn computes fully evolved 1D AGN disk structures, providing parametric radial profiles of key quantities such as temperature, density, and related disk properties.

Typical applications include:

• Migration torques in AGN disks
• Formation and evolution of compact objects embedded in gas disks
• Benchmarking and comparison with more complex AGN disk models

Development and Release Workflow

1. Build the package:

   python -m build

   This generates .whl and .tar.gz files in the dist/ directory.

2. Test locally:

   pip install dist/pagn-x.y.z-py3-none-any.whl

3. Upload to TestPyPI:

   twine upload --repository testpypi dist/*

4. Test installation from TestPyPI:

   pip install --index-url https://test.pypi.org/simple/ pagn

5. If successful, upload to PyPI:

   twine upload dist/*
