| Description |
NASA/IPAC Extragalactic Database (NED) Local Volume Sample (NED-LVS) is a subset of objects in NED with distances out to 1000 Mpc. Photometry from all-sky surveys (GALEX, 2MASS, and AllWISE) that have been joined into NED are also extracted, with the majority of NED-LVS objects having at least one measurement. These fluxes are used to derive physical properties (SFR and stellar mass) and to estimate the completeness relative to expected local luminosity densities. This sample of galaxies can be used for a wide range of astrophysical studies: star formation, galaxy evolution, large scale structure, follow-up searches to gravitational wave events, etc. This service provides the version of NED-LVS used in the analysis of Cook et al. (2023) as well as future updates that are used in the NED Gravitational Wave Follow-up service. |
