Identification and follow up of electromagnetic counterparts of gravitational wave candidate events
The LIGO Scientific Collaboration (LSC) and the Virgo Collaboration have started taking data in 2015, and we expect the sensitivity of the network to improve over time. Gravitational-wave transient candidates will be identified promptly upon acquisition of the data; we aim for distributing information with an initial latency of a few tens of minutes initially, possibly improving later. The LSC and the Virgo Collaboration (LVC) wish to enable multi-messenger observations of astrophysical events by GW detectors along with a wide range of telescopes and instruments of mainstream astronomy.
In 2012, the LVC approved a statement (LSC, Virgo) that broadly outlines LVC policy on releasing GW triggers (partially-validated event candidates). Initially, triggers will be shared promptly only with astronomy partners who have signed a Memorandum of Understanding (MoU) with LVC involving an agreement on deliverables, publication policies, confidentiality, and reporting. After four GW events have been published, further event candidates with high confidence will be shared immediately with the entire astronomy community (and the public), while lower-significance candidates will continue to be shared promptly only with partners who have signed an MoU.
From June to October 2013, we organized rounds of consultations with groups of astronomers that have expressed interest in the GW-EM follow-up program. Thanks to these consultations, we defined the framework and guiding rules for this program that are detailed here and collected into a standard MoU template.
Open calls for proposals to sign the standard MoU with LVC were issued in December 2013 and December 2014. Over 70 teams of professional astronomers and agencies have signed an MoU with LVC so far.
Third open call for participation in GW-EM follow-up program
The third open call for proposals to sign the standard MoU with LVC has been issued in December 2015 with deadline February 7, 2016. This call is open to all professional astronomers with demonstrated experience, and requires a partner to bring useful observing resource(s), not just astronomy expertise, to participate. GW triggers will be sent to these groups in the course of next observing runs circa 2016-2017 ( arXiv:1304.0670, LIGO-P1200087, VIR-0288A-12).
