Description

Weak gravitational lensing induces scatter in measurements of the luminosity distance-redshift relation. I show that incorporating weak lensing in standard siren analyses enables new probes of cosmic structure. As an illustration, I present a forecast for measuring the variance of matter perturbations, alongside the Hubble constant and matter abundance, using simulated bright sirens representative of ET and LISA observations.
