Cosmological model selection from standard siren detections by
  third-generation gravitational wave obervatories
  The multi-messenger observation of GW170817 enabled the first historic
measurement of the Hubble constant via a standard siren, so-called in analogy
to standard candles that enabled the measurement of the luminosity distance
versus redshift relationship at small redshift. In the next decades,
third-generation observatories are expected to detect hundreds to thousand of
gravitational wave events from compact binary coalescences with potentially a
joint electromagnetic counterpart. In the present work, we show how future
standard siren detections can be used within the framework of Bayesian model
selection to discriminate between cosmological models differing by the
parameterization of the late-time acceleration. In particular, we found
quantitative conditions for the standard LCDM model to be favored with respect
to other models with varying dark energy content, by reducing the uncertainty
in the gravitational determination of the luminosity distance with respect to
current expectations.
