The January 2025 version of NED-Local Volume Sample (NED-LVS) includes
new objects ingested by NED and the removal of newly identified non-galaxy
contaminants. This updated version contains a total of 2.07M objects, an
increase of 203K (10%) over the previous version, where 30K of the newly
added objects (after contaminant removal) are from the literature
and 173K originate from the Dark Energy Spectroscopic Instrument Early Data Release
(DESI-EDR; DESI Collaboration, 2024). Each release of NED-LVS is accompanied
by an additional round of vetting of both newly ingested objects and those
from the previous version to ensure that this sample will provide a robust
and highly complete census of the local Universe.

Beginning Feb 10, 2025 NED Gravitational Wave Follow-up (NED-GWF) Service
utilizes the updated version of NED-LVS (January 2025) which includes new
objects ingested by NED and the removal of newly identified non-galaxy contaminants.

The NED Local Volume Sample (NED-LVS) is a subset of ~2 million objects in NED with distances out to 1000 Mpc. The distances selected for NED-LVS are based on both redshifts (~99%) and redshift-independent distances, where the latter are prioritized at distances less than 200 Mpc. Photometry from al...

The January 2025 NED software release is now public. This includes:
- Database relations and query software for photometry have major updates.
- Photometry (SED) and spectral line data are now presented in separate tables (tabs).
- SED plots now have flux (nuF_nu) on the Y axis by default (changeable in the UI).
- Search results containing multiple objects now include coordinates in decimal degrees and sexagesimal formats.
- Cone search for objects near an input name or position includes support for IAU style inputs and redshift constraints.
- A new version of the IPAC Firefly UI framework used for interactive tables and graphics provides a modernized look and supports dark mode.

The February 2024 release of NED is out!

This includes:
- 172K new object links to over 800 new references,
- 162K new redshift measurements were added, including data for 24K objects that previously had no redshift

Additionally, the NED gravitational wave follow-up service
https://ned.ipac.caltech.edu/NED::GWFoverview/
is continuing to cross-match galaxies with LIGO-Virgo-KAGRA (LVK) GW events for the fourth observing run. The prioritization scheme is based on the joint WISE luminosity and the 3D volume probabilities, and the NED-LVS galaxy sample (Cook et al. 2023 https://ned.ipac.caltech.edu/uri/ADS::Bibcode/2023ApJS..268...14C)

The purpose of this NED service is to facilitate searches for electromagnetic (EM) counterparts to gravitational wave (GW) events. Within minutes after the Laser Interferometer Gravitational-Wave Observatory (LIGO)-Virgo-Kagra collaboration (LVK) issues an alert using the General Coordinates Network...
