TARDIS is a Monte Carlo radiative-transfer spectral synthesis code for 1D models of supernova ejecta. It is designed for rapid spectral modelling of supernovae. The code is described in this documentation and Kerzendorf & Sim 2014.


This documentation is currently under construction and does not describe all of the modes of operations available for TARDIS.

The code is built on a few principles:

  • open - the code is fully open source and we invite usage and contributions from the community
  • modular - the code has different microphysics modules and can be easily extended
  • fast - the code is geared towards rapid spectral synthesis to fit supernovae and other transients
  • easy - the code is designed to be easily installed and run as well as a detailed documentation

We encourage you to subscribe to tardis-sn-user to ask questions about TARDIS.

If you use this code for any publications or presentations please acknowledge it accordingly. For this first version please mention the website and cite Kerzendorf & Sim 2014.

User modifications and additions that lead to publications need to be handed back to the community by incorporating them into this publicly available version of TARDIS.

The current stable version of TARDIS is 0.9 and can be downloaded here, further installation instructions are available here Installation.

A file containing an example configuration file and an atomic database can be found in the section Running TARDIS

If you’re interested in contributing to the code, either contact us or you can contribute directly via github. We are using Astropy’s excellent workflow - more details can be found at http://astropy.readthedocs.org/en/latest/development/workflow/index.html.


Currently TARDIS only works on 64-bit python installations. We’re working on making it work on 32-bit python distributions.
