TDCOSMO 2025: Cosmological constraints from strong lensing time delays
TDCOSMO Collaboration, Simon Birrer, Elizabeth J. Buckley-Geer +30
We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar…
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…
Consequences of the lack of azimuthal freedom in the modeling of lensing galaxies
Lyne Van de Vyvere, Dominique Sluse, Matthew R. Gomer +1
Massive elliptical galaxies can display structures that deviate from a pure elliptical shape, such as a twist of the principal axis or variations in the axis ratio with galactocent…
TDCOSMO. VII. Boxyness/discyness in lensing galaxies : Detectability and impact on
Lyne Van de Vyvere, Matthew R. Gomer, Dominique Sluse +4
In the context of gravitational lensing, the density profile of lensing galaxies is often considered to be perfectly elliptical. Potential angular structures are generally ignored,…
