4 April 2024: The LIGO-Virgo-KAGRA Collaboration (LVK) is migrating all of the content of this wiki and future communications related to multi-messenger astrophysics to the OpenMMA Forum hosted by SCiMMA (https://scimma.org/). All subscribers to the OpenLVEM mailing list have been migrated to openmma@lists.illinois.edu which will soon be given a scimma.org email address. All future communications from the LVK will go through the OpenMMA Forum and mailing list.This is the community forum on multi-messenger observations connected to Gravitational Wave (GW) transient event detections.
