Galaxy Mentions HATS
A HATS catalog of 43,546 resolved literature mentions from
astronolan/galaxy-mentions,
prepared for efficient spatial crossmatching with the
Multimodal Universe HATS catalogs.
Each row is a mention in a paper, not a deduplicated astronomical object. Multiple rows may
therefore describe the same galaxy. The optional wiki_entity_id groups mentions using the current
1 arcsecond connected-components build, while mention_id remains the unique row identifier.… See the full description on the dataset page: https://huggingface.co/datasets/astronolan/galaxy-mentions-hats.galaxy_descriptions_hats
Galaxy Descriptions (HATS)
Original dataset: Nolan Koblischke's astronolan/galaxy-descriptions
This is the same dataset, repartitioned into the spatially indexed HATS format. The scientific content is unchanged.
This catalog contains the original 275,613 galaxy rows, including images, captions, summaries, text embeddings, AION image embeddings, coordinates, survey names, and object identifiers. Conversion added the HATS _healpix_29 spatial index and organized the rows into… See the full description on the dataset page: https://huggingface.co/datasets/Smith42/galaxy_descriptions_hats.TeVCat_HATS
TeVCat in HATS format
A snapshot of TeVCat, the online catalog of TeV gamma-ray sources, converted to the HATS format so it can be queried and crossmatched with LSDB alongside other HATS catalogs, such as those from the Multimodal Universe.
