Open Supernova Catalog is a community-driven, open-access database aggregating photometric, spectroscopic, and metadata for observed supernovae and related transients. It serves researchers across observational astronomy, theoretical astrophysics, and time-domain surveys by consolidating heterogeneous data from observatories, surveys, and published literature. The project interfaces with major facilities, archives, and collaboration networks to enable reproducible analysis and cross-matching with complementary catalogs.
The catalog aggregates observations from projects such as Palomar Transient Factory, Zwicky Transient Facility, All-Sky Automated Survey for Supernovae, Pan-STARRS, and Gaia alongside historical records compiled from journals like The Astrophysical Journal, Monthly Notices of the Royal Astronomical Society, and Astronomy & Astrophysics. It integrates releases and alerts from infrastructure including Transient Name Server, International Astronomical Union, NASA Exoplanet Archive, and datasets hosted at Harvard–Smithsonian Center for Astrophysics and European Southern Observatory. Contributors include teams affiliated with institutions such as California Institute of Technology, Max Planck Institute for Astrophysics, University of California, Berkeley, and University of Cambridge. The resource is designed to interoperate with tools developed by communities around Astropy, IRAF, TOPCAT, and Jupyter Notebook workflows.
Entries contain multi-band photometry, time-series spectroscopy, classification metadata, redshifts, coordinates, and provenance linking to surveys and publications. The schema harmonizes inputs from facilities like Subaru Telescope, Very Large Telescope, Keck Observatory, and Gemini Observatory and catalogs such as Sloan Digital Sky Survey and 2MASS. Data formats include plain-text light curves, FITS spectra, and JSON/CSV metadata suitable for ingestion by systems developed at Space Telescope Science Institute, National Optical-Infrared Astronomy Research Laboratory, and data platforms inspired by Virtual Observatory standards. Cross-references to host galaxies pull from resources like Sloan Digital Sky Survey and NASA/IPAC Extragalactic Database.
Users access the database via web interfaces, bulk downloads, and programmatic APIs designed to work with scripting in Python (programming language), R (programming language), and command-line environments common at CERN and university data centers. Integration points include notebooks hosted on platforms such as GitHub, Binder, and cloud services used by groups at European Space Agency and NASA. Visualization and analysis tooling supports interoperability with Matplotlib, NumPy, Pandas (software), and community software from teams at University of Washington and University of Chicago.
Initiated in the mid-2010s, the effort coordinated contributors from open-science advocates at institutions including California Institute of Technology, Harvard University, and Max Planck Society. Development used platforms such as GitHub for version control and issue tracking, drawing design inspiration from projects like Simbad and Vizier. Milestones include ingestion of legacy photographic-era data compiled by researchers formerly at Carnegie Institution for Science and bulk imports of survey-era discoveries from Pan-STARRS and Zwicky Transient Facility teams. Funding and support have intersected with initiatives at National Science Foundation, European Research Council, and philanthropic programs connected to institutions such as Simons Foundation.
The project operates under an open contribution model with provenance policies and data licensing choices influenced by standards at Creative Commons and data-sharing norms established by publishers like Oxford University Press and Elsevier. Governance relies on volunteer maintainers, steering contributors from organizations like American Astronomical Society, regional working groups tied to International Astronomical Union, and academic labs at University of California, Santa Cruz and University of Toronto. Contribution workflows employ pull requests, issue triage, and continuous integration practices common in software projects at Google and Microsoft Research.
Researchers use the catalog for population studies of explosion mechanisms tested against models from groups at Harvard–Smithsonian Center for Astrophysics and Max Planck Institute for Astrophysics, for training machine-learning classifiers developed at Stanford University and Massachusetts Institute of Technology, and for follow-up planning coordinated with facilities like Keck Observatory and Very Large Telescope. The resource supports undergraduate and graduate instruction at universities including University of Cambridge and University of California, Berkeley and underpins citizen-science efforts similar to those organized by Zooniverse. Citations appear in papers across The Astrophysical Journal and Monthly Notices of the Royal Astronomical Society.
Current limitations include incompleteness for faint, fast-evolving transients discovered by surveys such as LSST (Vera C. Rubin Observatory) and heterogeneity in calibration between instruments like Hubble Space Telescope and ground-based telescopes. Future plans emphasize enhanced metadata standards aligned with International Virtual Observatory Alliance recommendations, automated ingestion pipelines inspired by work at Space Telescope Science Institute, tighter cross-matching with catalogs such as Gaia and Pan-STARRS, and expanded support for spectropolarimetry and multi-messenger associations with facilities like LIGO–Virgo Collaboration and IceCube Neutrino Observatory.
