Galaxies Hosting Supernovae and other Transients (GHOST)

Mastodon

GHOST refers to a database of ~16,175 supernovae and the photometric properties of their host galaxies. Photometry is provided by the Pan-STARRS 3-pi survey in the Northern Hemisphere, and SkyMapper in the Southern Hemisphere. GHOST also refers to the software to associate new transients with host galaxies. The package is actively maintained - if there’s a feature you’d like to see, please get in touch!
