Strong lensing cross sections for isothermal models - I. Finite source effects in the circular case
Vanessa P. de Freitas, Martin Makler, Habib S. Dúmet-Montoya
The strong galaxy-galaxy lensing produces highly magnified and distorted images of background galaxies in the form of arcs and Einstein rings. Statistically, these effects are quan…
Observation and Confirmation of Six Strong Lensing Systems in The Dark Energy Survey Science Verification Data
B. Nord, E. Buckley-Geer, H. Lin +89
We report the observation and confirmation of the first group- and cluster-scale strong gravitational lensing systems found in Dark Energy Survey (DES) data. Through visual inspect…
Analytic Solutions for Navarro--Frenk--White Lens Models for Low Characteristic Convergences
H. S. Dúmet-Montoya, G. B. Caminha, M. Makler
The Navarro-Frenk-White (NFW) density profile is often used to model gravitational lenses. For low values of the characteristic convergence () of this model - correspond…
On the accuracy of the Perturbative Approach for Strong Lensing: Local Distortion for Pseudo-Elliptical Models
Habib S. Dúmet-Montoya, Gabriel B. Caminha, Bruno Moraes +3
The Perturbative Approach (PA) introduced by \citet{alard07} provides analytic solutions for gravitational arcs by solving the lens equation linearized around the Einstein ring sol…
Domain of validity for pseudo-elliptical NFW lens models
H. S. Dúmet-Montoya, G. B. Caminha, M. Makler
Models with elliptical potentials (pseudo-elliptical) are often used in gravitational lensing applications. Nevertheless, they generally lead to nonphysical mass distributions in s…
