Merging compact binaries are the most viable and best studied candidates forgravitational wave (GW) detection by the fully operational network ofground-based observatories. In anticipation of the first detections, theexpected distribution of GW sources in the local universe is of considerableinterest. Here we investigate the full phase space distribution of coalescingcompact binaries at $z = 0$ using dark matter simulations of structureformation. The fact that these binary systems acquire large barycentricvelocities at birth ("kicks") results in merger site distributions that aremore diffusely distributed with respect to their putative hosts, with mergersoccurring out to distances of a few Mpc from the host halo. Redshift estimatesbased solely on the nearest galaxy in projection can, as a result, beinaccurate. On the other hand, large offsets from the host galaxy could aid thedetection of faint optical counterparts and should be considered when designingstrategies for follow-up observations. The degree of isotropy in the projectedsky distributions of GW sources is found to be augmented with increasing kickvelocity and to be severely enhanced if progenitor systems possess large kicksas inferred from the known population of pulsars and double compact binaries.Even in the absence of observed electromagnetic counterparts, the differencesin sky distributions of binaries produced by disparate kick-velocity modelscould be discerned by GW observatories, within the expected accuracies anddetection rates of advanced LIGO--in particular with the addition of moreinterferometers.
