Recently, Fermi GBM detected a short GRB~170817A. It is reported to have a redshift of 0.0098. Assuming this is true, it will have two profound implications: (1) the isotropic-equivalent $\\gamma$-ray energetics, E$_{iso,\\gamma}$, of GRB~170817A is only about 4 $imes$ 10$^{...
GRB170817A, associated with the LIGO-Virgo GW170817 neutron-star merger event, lacks the short duration and hard spectrum of a Short gamma-ray burst (GRB) expected from long-standing classification models. Correctly identifying the class to which this burst belongs requires comparison with other G...
This is why previously no thermal-like kilonova component has been identified at such an early time7,8,9,10,11,12,13 except in the off-axis dim GRB 170817A (refs. 14,15,16,17,18,19) associated with GW170817 (ref. 20). Here we report the identification of an unusual optical ...

However, its status as a GRB was confirmed with the X-ray light curve decaying as expected for a GRB afterglow [87], and subsequently, a redshift determination of 0.151 [88,89,90]. Most unusually, many facilities, including Fermi, AGILE, Konus-Wind, and INTEGRAL, reported detecting X-...
