Asiago Supernova Catalog: Dynamic Catalog of Supernovae and Parent Galaxies

The Asiago Supernova Catalog is a dynamic version superseding the 1999 original, containing data on supernovae observed since 1885 and their parent galaxies. NASA's HEASARC created this table based on the CDS Catalog B/sn, which is updated regularly, with the HEASARC version updated within a week of CDS updates. The literature has been searched for new information on both newly discovered and past supernovae, and parent galaxy data have been homogenized.

Use Cases

• Analyze supernova discovery trends over time based on the catalog's temporal coverage since 1885.
• Study correlations between supernova properties and host galaxy characteristics based on the homogenized parent galaxy data.
• Track updates and new discoveries in supernova research based on the catalog's dynamic, regularly updated nature.

Strengths

• Contains data on supernovae observed since 1885, providing a long historical baseline.
• Regularly updated by CDS, with the HEASARC version updated within a week, suggesting ongoing maintenance.
• Includes homogenized data for parent galaxies, which may improve cross-comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
