We estimate the rate of lensed BNS events resolvable by LIGO and Virgo and find that it is constrained by the current non-detection of a stochastic GW background. Following closely the formalism we developed previously (arXiv:2006.04516v2 [astro.ph.CO]) in the context of binary black hole lensing, we show that at current sensitivities the fraction of BNS coalescences with lensing magnifications $\\mu> 1.02$ is less than $\\sim 7\\times 10^{-8}$ and therefore such events should not be expected in the near future. We also make predictions for projected future sensitivities.", "revisions": [ { "version": "v1", "updated": "2020-08-24T18:00:02.000Z" } ], "analyses": { "keywords": [ "binary neutron star", "stochastic background", "stochastic gw background", "bns events", "gravitational wave" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable" } } }
