Database of supernovae and the photometric and spectroscopic properties of their host galaxies

“At the last dim horizon, we search among ghostly errors of observations for landmarks that are scarcely more substantial. The search will continue. The urge is older than history. It is not satisfied and it will not be oppressed.” –Edwin Hubble

GHOST

Welcome to GHOST, the database for supernovae and their host galaxies. This database contains ~16k sources in PS1, which were used to predict supernova classes in Gagliano et al. (2020). Installation instructions for the analysis tools are below.

Installation

For details on installing and using GHOST, see the documentation.

Contributing

We love contributions! astro_ghost is open source, built on open source, and we’d love to have you hang out in our community.

Imposter syndrome disclaimer: We want your help. No, really.

There may be a little voice inside your head that is telling you that you’re not ready to be an open source contributor; that your skills aren’t nearly good enough to contribute. What could you possibly offer a project like this one?

We assure you - the little voice in your head is wrong. If you can write code at all, you can contribute code to open source. Contributing to open source projects is a fantastic way to advance one’s coding skills. Writing perfect code isn’t the measure of a good developer (that would disqualify all of us!); it’s trying to create something, making mistakes, and learning from those mistakes. That’s how we all improve, and we are happy to help others learn.

Note: This disclaimer was originally written by Adrienne Lowe for a PyCon talk, and was adapted by astro_ghost based on its use in the README file for the MetPy project.
