GW170817: Implications for the local kilonova rate and for surveys from ground-based facilities

We compute the local rate of events similar to GRB 170817A, which has been recently found to be associated with a kilonova (KN) outburst. Our analysis finds an observed rate of such events of R KN ~ 352 -281 +810 Gpc -3 yr -1 . After comparing at their face values this density of sGRB outbursts with...
