Query: Beyond Concordance Cosmology with Magnification of Gravitational-Wave
  Standard Sirens   We show how future gravitational-wave detectors would be able of
discriminating between the concordance LCDM cosmological model and up-to-date
competing alternatives, e.g. dynamical dark energy models (DE) or modified
gravity theories (MG). Our method consists in using the weak-lensing
magnification effect that affects a standard-siren signal because of its
travelling trough the Universe's large-scale structure. As a demonstration, we
present constraints on DE and MG from proposed gravitational-wave detectors,
namely ET and DECIGO/BBO.
