Exploiting the diversity of modeling methods to probe systematic biases in strong lensing analyses
A. Galan, G. Vernardos, Q. Minor +3
Challenges inherent to high-resolution and high signal-to-noise data as well as model degeneracies can cause systematic biases in analyses of strong lens systems. In the past decad…
On the ellipticity parameterization for an NFW profile: an overlooked angular structure in strong lens modeling
Matthew R. Gomer, Dominique Sluse, Lyne Van de Vyvere +3
Galaxy-scale gravitational lenses are often modeled with two-component mass profiles where one component represents the stellar mass and the second is an NFW profile representing t…
TDCOSMO VIII: A key test of systematics in the hierarchical method of time-delay cosmography
Matthew R. Gomer, Dominique Sluse, Lyne Van de Vyvere +2
The largest source of systematic errors in the time-delay cosmography method likely arises from the lens model mass distribution, where an inaccurate choice of model could in princ…
Galaxy-lens determination of : the effect of the ellipse+shear modeling assumption
Matthew R. Gomer, Liliya L. R. Williams
Galaxy lenses are frequently modeled as an elliptical mass distribution with external shear and isothermal spheres to account for secondary and line-of-sight galaxies. There is sta…
