Measuring the redshift of standard sirens using the neutron star
  deformability
  A recent study has shown that redshift information can be directly extracted
from gravitational wave sources. This can be done by exploiting the tidal
phasing contributions to the waveform during the inspiral phase of binary
neutron stars coalescences. The original study investigated the viability of
this idea in the context of the Einstein Telescope using a Fisher Matrix
approach and in this paper, we further explore this idea using realistic
simulations and Bayesian inference techniques. We find that the fractional
accuracy with which the redshift can be measured is in the order of tens of
percent, in agreement with Fisher Matrix predictions. Moreover, no significant
bias is found. We conclude that, when tidal phasing contributions are included
in the analysis, inference of the cosmological parameters from gravitational
waves is possible
