The unWISE Catalog has two advantages over the existing WISE catalog (AllWISE): first, it is based on significantly deeper imaging, and second, it features improved modeling of crowded regions. The deeper imaging used in the unWISE Catalog comes from the coaddition of all publicly available 3-5 micron WISE imaging, including that from the ongoing NEOWISE-Reactivation mission, thereby increasing the total exposure time by a factor of 5 relative to AllWISE. At these depths, even at high Galactic latitudes many sources are blended with their neighbors; accordingly, the unWISE analysis simultaneously fits thousands of sources to obtain accurate photometry. The unWISE catalog detects sources at 5 sigma roughly 0.7 magnitudes fainter than the AllWISE catalog and more accurately models millions of faint sources in the Galactic plane, enabling a wealth of Galactic and extragalactic science. In particular, relative to AllWISE, unWISE doubles the number of galaxies detected between redshifts 0 and 1 and triples the number between redshifts 1 and 2, cataloging more than half a billion galaxies over the whole sky.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://irsa.ipac.caltech.edu/data/WISE/unWISE/gator_docs/unwise_colDescriptions.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://irsa.ipac.caltech.edu/SCS?table=unwise_2019&", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "ivo://irsa.ipac/wise/catalog/unwise", "keyword": ["__"], "landingPage": "ivo://irsa.ipac/wise/catalog/unwise", "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/IPAC Infrared Science Archive"}, "theme": ["Astrophysics"], "title": "unWISE Catalog"}
