A Fuzzy Situation Eased: Cold Dark Matter with Multipoles Can Explain The Double Radio Quad Lens HS 0810+2554
John H. Miller, Liliya L. R. Williams
Originally observed in isophotal density contours of elliptical galaxies, higher order perturbations in the form of Fourier modes, or multipoles, are becoming increasingly recogniz…

Are Models of Strong Gravitational Lensing by Clusters Converging or Diverging?
Derek Perera, John H Miller, Liliya L. R. Williams +4
The increasingly large numbers of multiple images in cluster-scale gravitational lenses have allowed for tighter constraints on the mass distributions of these systems. Most lens m…

Elucidating Galaxy Population Properties Using a Model-Free Analysis of Quadruply Imaged Quasar Lenses From Large Surveys
John Miller, Liliya L. R. Williams
The population of strong lensing galaxies is a sub-set of intermediate-redshift massive galaxies, whose population-level properties are not yet well understood. In the near future,…
