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…

OpenCosmo: Community Portal and Analysis Framework for Flagship Cosmological Simulations
Patrick R. Wells, Michael Buelhmann, Patricia Larsen +11
Cosmology is a precision observational science, and large simulations are necessary components of many analyses. These simulations are computationally expensive and produce massive…

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…
