Gravitational Lensing By a Massive Object in a Dark Matter Halo. II. Shear, Phase, and Image Geometry

Michal Karamazov, David Heyrovsky

We study the gravitational lensing influence of a massive object in a dark matter halo, using a simple model of a point mass embedded in a spherical Navarro--Frenk--White halo. Bui…

Gravitational Lensing By a Massive Object in a Dark Matter Halo. I. Critical Curves and Caustics

Michal Karamazov, Lukas Timko, David Heyrovsky

We study the gravitational lensing properties of a massive object in a dark matter halo, concentrating on the critical curves and caustics of the combined lens. We model the system…
