NumFOCUS is pleased to announce the newest addition to our fiscally sponsored projects: TARDIS

TARDIS is an open-source, Monte Carlo based radiation transport simulator for supernovae ejecta. TARDIS simulates photons traveling through the outer layers of an exploded star including relevant physics like atomic interactions between the photons and the expanding gas. The TARDIS collaboration is a diverse group of astrophysicists, software engineers, computer scientists, and statisticians who all cooperate to maintain and develop the codebase in addition to publishing scientific papers.

“TARDIS is designed from the ground up to be a multi-disciplinary research and training code. We are thrilled to have found an ally in NumFOCUS who will help us move forward in our groundbreaking scientific approach.”

Wolfgang Kerzendorf, Assistant Professor of Astrophysics and Data Science at Michigan State University

This collection of tools is able to analyze observations from exploding stars and is widely adopted in the astrophysical community for cutting edge science. The collaboration applies new tools from artificial intelligence research and high-performance computing. TARDIS uses a standard open-source community software development workflow relying on GitHub for development, testing, and continuous integration.

TARDIS is currently being used in modeling the observations of exploding stars and other astrophysical transients. These include but are not limited to exploding white dwarf stars, massive stars undergoing a core-collapse, and coalescing neutron stars.
