This includes:
- 368K sources from the literature were ingested, including 316K cross-matches with NED objects
and 52K new objects, increasing NED objects with redshifts by 104K.
- 80K satellites and background objects with spectroscopic redshifts around nearby galaxies from the
Satellites Around Galactic Analogs (SAGA; Mao et al., 2024) survey.
- 11K new galaxies at intermediate to high redshifts from HST (WISP; Battisti et al., 2024)
and JWST (JADES; D'Eugenio et al., 2025) studies.
- The Object Type field in NED is now separated into Physical Types (e.g., G, GPair, QSO), where available,
and a new EM Region field (e.g., Vis, Xray).
