LightCurveLynx
A Fast and Nimble Package for Time Domain Astronomy
Introduction
Realistic light curve simulations are essential to many time-domain problems. Simulations are needed to evaluate observing strategy, characterize biases, and test pipelines. LightCurveLynx aims to provide a flexible, scalable, and user-friendly time-domain simulation software with realistic effects and survey strategies.
The software package consists of multiple stages:
- A flexible framework for consistently sampling model parameters (and hyperparameters),
- Realistic models of time varying phenomena (such as supernovae and AGNs),
- Effect models (such as dust extinction), and
- Survey characteristics (such as cadence, filters, and noise).
For an overview of the package, we recommend starting with introduction notebook.
Installation
Install from PyPI or conda-forge:
pip install lightcurvelynx
conda install conda-forge::lightcurvelynx
Since LightCurveLynx relies on a large number of existing packages, not all of the packages are installed in the default configuration. You can install most of the optional depenencies with the "dev" or "all" extras:
pip install 'lightcurvelynx[all]'
If you need a package that is not installed as part of the default or all configurations, LightCurveLynx will provide a message with the information on which packages you need to install and how to install them.
Example Usage
The tutorial notebooks documentation page provides a variety of usage examples and technical deep dives.

Dev Guide - Getting Started
Before installing any dependencies or writing code, it's a great idea to create a
virtual environment such as venv
>> python3 -m venv ~/envs/lightcurvelynx
>> source ~/envs/lightcurvelynx/bin/activate
Once you have created a new environment, you can install this project for local development using the following commands:
>> pip install -e .'[dev]'
>> pre-commit install
Notes:
- The single quotes around
'[dev]'may not be required for your operating system. pre-commit installwill initialize pre-commit for this local repository, so that a set of tests will be run prior to completing a local commit. For more information, see the Python Project Template documentation on pre-commit
If you are interested in contributing directly to the package, see our contribution guide.
