Description
Current searches for microlensing signatures in the detected gravitational wave (GW) events assume an isolated point mass lens (PML) model. However, the assumption of the lenses being isolated is overly simplistic, as these lenses are typically embedded within more complex structures, such as galaxies. In this paper, we extend the current lens model to incorporate external influences that better reflect the environment in which these lenses reside. Specifically, we consider microlenses perturbed by singular isothermal sphere (SIS) galaxy potentials. We find that neglecting host galaxy effects may lead to reduced sensitivity in microlensing searches.
