TDCOSMO XXXI: New techniques in line-of-sight studies of time delay lenses
Daniel Johnson, Devon Williams, Chris Fassnacht +5
The distribution of matter along the same line of sight but external to the main lens, quantified by , is a key source of uncertainty in time delay cosmography and…
TDCOSMO. XXVII. JWST-based Lens Models and H Measurement of WFI2033, HE0435, and PG1115
D. M. Williams, T. Treu, D. P. Johnson +13
Time-delay cosmography offers a one-step, distance-ladder-independent route to the Hubble-Lemaitre constant, H_0. We present new cosmography-grade lens models of three quadruply im…
MAGNUS II: Rotational support of massive early-type galaxies decreased over the past 7 billion years
Pritom Mozumdar, Michele Cappellari, Christopher D. Fassnacht +1
Understanding how the internal kinematics of massive galaxies evolve is key to constraining the physical processes that drive their assembly. We investigate the evolution of rotati…
MAGNUS I: A MUSE-DEEP Sample of Early-type Galaxies at Intermediate Redshift
Pritom Mozumdar, Michele Cappellari, Christopher D. Fassnacht +1
We present a sample of 213 early-type galaxies (ETGs) at redshifts . We combine deep integral-field spectroscopy from the MUSE-DEEP survey with high-resolution HST…
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…
