The Panchromatic Afterglow of GW170817

Posted 01 Dec 2021: We present the full panchromatic afterglow light curve data of GW170817, including new radio data as well as archival optical and X-ray data, between 0.5 and 940 days post-merger. Measurements are obtained for the light curve shape parameters, time of peak, magnetic field strength, electron power-law distribution and density of the circum-merger environement. Study reported in Makhathini et al. 2021. Read more news items.

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.
