Description
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.
Provenance
Source
