CosmoTransitions (modernized)

A modern, test-driven update of CosmoTransitions for studying first-order phase transitions (FOPTs) and their gravitational-wave signatures — now in Python 3.13, with clearer APIs, numerical utilities, examples, and documentation.

Original project by Carroll L. Wainwright (MIT).
Modernization by Igor Almeida da Silva Gouvêa Stellet (advisor: Felipe Tovar Falciano).

Install (dev) & Quick Start

Requires Python 3.11+ (targeting 3.13). We recommend a fresh virtualenv.

python -m pip install -U pip
pip install -e .[dev]   # editable install with dev deps (pytest, ruff, black)
