Euclid Quick Data Release (Q1). The Strong Lensing Discovery Engine F -- Bright and low-redshift strong lenses
Euclid Collaboration, L. R. Ecker, M. Fabricius +346
We present 72 additional galaxy-galaxy strong lenses that complement the sample discovered in the Euclid Quick Release 1 data (63.1 deg^2) of the Strong Lens Discovery Engine (SLDE…
The Stellar IMF and Dark Matter Halo of ESO0286: Constraints from Strong Lensing and Dynamics
Han Wang, Jens Thomas, Mathias Lipka +4
The internal mass structure of elliptical galaxies offers critical insights into galaxy formation, yet disentangling stellar mass from dark matter and determining the stellar initi…
TDCOSMO XXIV. First spatially resolved kinematics of the lens galaxy obtained using JWST-NIRSpec to improve time-delay cosmography
Anowar J. Shajib, Tommaso Treu, Sherry H. Suyu +15
Spatially resolved stellar kinematics has become a key ingredient in time-delay cosmography to break the mass-sheet degeneracy in the mass profile and in turn provide a precise con…
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…
GPU-Accelerated Gravitational Lensing & Dynamical (GLaD) Modeling for Cosmology and Galaxies
Han Wang, Sherry H. Suyu, Aymeric Galan +4
Time-delay distance measurements from strongly lensed quasars provide a robust, independent method for determining the Hubble constant (). This approach cross-checks est…
