Steep decline in the radio light curve of GW170817

Posted 01 Oct 2018: Observations carried out with the VLA, ATCA, GMRT and MeerKAT telescopes indicate a steep decline of the radio light curve, which is a classic signature of a relativistic jet. Analytical calculation implies a viewing angle of about 15 deg and jet opening angle less than 5 deg. Read More

About JAGWAR

The Jansky VLA mapping of Gravitational Wave bursts as Afterglows in Radio (JAGWAR) is a dedicated observing program on the VLA telescope in New Mexico. It is designed to maximize the discovery of the radio counterparts of neutron star mergers detected by terrestrial gravitational-wave observatories (e.g. LIGO). The goals of JAGWAR are 1) to study the material that was ejected during the mergers, 2) map the environments of the mergers, 3) find a population of merger afterglows and study their demographics.
