March 2019 Release Highlights



  • We are pleased to announce a new service designed to leverage the data in NED to facilitate searches for electromagnetic counterparts of gravitational wave
    events. Within minutes after the Laser Interferometer Gravitational-Wave Observatory (LIGO)-Virgo collaboration issues a new GW alert on the NASA Gamma-ray Coordinates Network (GCN), NED responds by posting a list of candidate galaxies in the event’s 90% probability volume to help the community plan efficient follow-up observations. See Services » Gravitational Wave Followup.


  • This release also provides a number of improvements in the user interface, including Tools » Reference Lookup.


  • In the menu bar, the links to the Classic Home Page and Level 5 are now located under Services..
