| Description |
The NED GWF service facilitates searches for electromagnetic (EM) counterparts to gravitational wave (GW) events. Within minutes after the LIGO/Virgo/KAGRA collaboration issues an alert using the GCN - NASA's Time-Domain and Multimessenger Alert System (https://gcn.nasa.gov/), this NED service responds by cross-matching in 3D the event's HEALPix map with galaxies in the local Universe and the following results are provided: an all-sky image of the probability contours, the location of all galaxies in NED within the 90% probability volume, and the top 20 candidates. |
