TDCOSMO. XXIII. Measurement of the Hubble constant from the doubly lensed quasar HE1104-1805

Eric Paic, Frédéric Courbin, Christopher D. Fassnacht +18

Time-delay cosmography leverages strongly lensed quasars to measure the Universe's current expansion rate, H_0, independently from other methods. While the latest TDCOSMO results r…

HOLISMOKES XIX: SN 2025wny at , the first strongly lensed superluminous supernova

Stefan Taubenberger, Ana Acebron, Raoul Cañameras +45

We present imaging and spectroscopic observations of supernova SN 2025wny, associated with the lens candidate PS1 J0716+3821. Photometric monitoring from the Lulin and Maidanak obs…

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…

TDCOSMO XVII. New time delays in 22 lensed quasars from optical monitoring with the ESO-VST 2.6m and MPG 2.2m telescopes

Frédéric Dux, Martin Millon, Aymeric Galan +29

We present new time delays, the main ingredient of time delay cosmography, for 22 lensed quasars resulting from high-cadence r-band monitoring on the 2.6 m ESO VLT Survey Telescope…

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…
