We performed lens modeling for them using lenstronomy and constrained the mass and light distributions of the deflector galaxies using a sample of 15 strong lensing systems. We adopt the local galaxy density as a metric for the environment and test our results against several alternative definitions of it. This result supports using centroid offsets as a probe of dark matter theories since the environment’s impact on it can be treated as negligible.
