Numerous population syntheses (most often to populations of binaries where one or both members are NSs) can be found in the literature [86, 272, 322, 254, 173, 27]. A group in Moscow has made a web interface to their code . Although extremely instructive, the uncertain assumptions about initial conditions, the physics of mass transfer and the kicks applied to the compact object at birth result in a wide range of predicted event rates which are currently broader than the empirical methods [148, 157, 149]. Ultimately, the detection statistics from the gravitational wave detectors could provide far tighter constraints on the DNS merging rate than the pulsar surveys from which these predictions are made.
