  bibo_abstract:
  - The gravitational waves (GWs) emitted by inspiralling binary black holes, expected
    to be detected by the Laser Interferometer Space Antenna (LISA), could be used
    to determine the luminosity distance to these sources with the unprecedented precision
    of ≲1 per cent. We study cosmological parameter constraints from such standard
    sirens, in the presence of gravitational lensing by large-scale structure. Lensing
    introduces magnification with a probability distribution function (PDF) whose
    shape has significant skewness and kurtosis, and depends on cosmological parameters.
    We use Monte Carlo simulations to generate mock samples of standard sirens, including
    a small intrinsic scatter, as well as the additional, larger scatter from lensing,
    in their inferred distances. We derive constraints on cosmological parameters,
    by simultaneously fitting the mean and the distribution of the residuals on the
    distance versus redshift (dL–z) Hubble diagram. We find that for standard sirens
    at redshift z≈ 1, the sensitivity to a single cosmological parameter, such as
    the matter density Ωm, or the dark energy equation of state w, is ∼50–80 per cent
    tighter when the lensing PDF is used, compared to the sensitivity derived from
    a Gaussian PDF with the same variance. When these two parameters are constrained
    simultaneously, the non-Gaussian shape yields a further enhanced improvement (by
    ∼120 per cent), owing to the correlation between the parameters. The sensitivity
    to the amplitude of the matter power spectrum, σ8 from the cosmological dependence
    of the PDF alone, however, is ∼20 per cent worse than that from the Gaussian PDF.
    The improvements for Ωm and w arise purely from the non-Gaussian shape of the
    lensing PDF and can be attributed specifically to the sharpness of the peak of
    this PDF (i.e. to a finite kurtosis); the dependence of the PDF on these parameters
    does not improve constraints relative to those available from the mean dL–z relation.
    At higher redshifts, the PDF resembles a Gaussian more closely, and the effects
    of the non-Gaussianities become less prominent. These results highlight the importance
    of obtaining an accurate and reliable PDF of the lensing convergence, in order
    to realize the full potential of standard sirens as cosmological probes.@eng
