Gravitational lensing by an ellipsoidal Navarro--Frenk--White dark-matter halo: An analytic solution and its properties
David Heyrovský, Michal Karamazov
The analysis of gravitational lensing by galaxies and galaxy clusters typically relies on ellipsoidal lens models to describe the deflection of light by the involved dark-matter ha…

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…
