September 2024 Release Highlights

Database Contents

The Dark Energy Spectroscopic Instrument Early Data Release (DESI-EDR; DESI Collaboration, 2024) catalog has been integrated into NED. DESI-EDR includes measured properties such as positions, object types (galaxy, star, QSO) and redshift information for 1.85 million unique objects, out of which 70% were cross-matched with existing objects and 30% became new objects in NED. Please refer to Holdings » Data Sets » DESI-EDR for more information on the catalog integration and validation.

Tabular summaries of NED's current holdings are presented here. Graphic summaries are presented here, updated with plots from the NED Local Volume Sample (NED-LVS; Cook et al. 2023), assessing the completeness of the galaxy census per unit volume.
