Gravitational-wave Seminar: GW170817/GRB 170817A/AT2017gfo/afterglow: what did the first NS-NS merger event tell us?

Speaker: Prof. Bing Zhang (University of Nevada and PKU)Abstract: The first NS-NS merger event detected by the humankind, GW170817, was associated with a short GRB 170817A, a thermal optical transient AT2017gfo, and a broad-band (radio to X-rays) afterglow. I will critically review the observational data and various ideas of interpreting this watershed event, and present my understanding of the event regarding its jet launching mechanism, jet structure, jet dissipation mechanism, origin of the ``kilonova’’and broadband afterglow, as well as the possible merger product.
