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…
Investigating The Effects of Early Dark Energy on Large-scale Structure Within the EDENS Suite
Sophie Hodgson, Patrick Wells, Katrin Heitmann +1
Early Dark Energy (EDE) models have been suggested as a possible solution to the so-called Hubble Tension, a discrepancy of the measurement of the Hubble constant at early and late…
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. XVI. Measurement of the Hubble Constant from the Lensed Quasar WGD20384008
Kenneth C. Wong, Frédéric Dux, Anowar J. Shajib +17
Time-delay cosmography is a powerful technique to constrain cosmological parameters, particularly the Hubble constant (). The TDCOSMO collaboration is performing an ongoing…
TDCOSMO XV: Population Analysis of Lines of Sight of 25 Strong Galaxy-Galaxy Lenses with Extreme Value Statistics
Patrick R. Wells, Christopher D. Fassnacht, Simon Birrer +1
Time-Delay Cosmography is a technique for measuring with strong gravitational lensing. It requires a correction for line of sight perturbations, and it is necessary to build…
