Decline in the radio light curve of GW170817

Posted 21 Mar 2018: The well-sampled radio light curve of GW170817 obtained with the VLA and ATCA telescopes indicates a peak at 150 days followed by a decline in radio emission. The rate of decline is most consistent with mildly- or non-relativistic material and there is no clear evidence for an energetic off-axis jet. 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.
