TDCOSMO VI: Distance Measurements in Time-delay Cosmography under the Mass-sheet transformation

Geoff C. -F. Chen, Christopher D. Fassnacht, Sherry H. Suyu +3

Time-delay cosmography with gravitationally lensed quasars plays an important role in anchoring the absolute distance scale and hence measuring the Hubble constant, $H_{0}$ , indepe…

TDCOSMO IV: Hierarchical time-delay cosmography -- joint inference of the Hubble constant and galaxy density profiles

S. Birrer, A. J. Shajib, A. Galan +24

The H0LiCOW collaboration inferred via gravitational lensing time delays a Hubble constant $H_{0} = 73. 3_{- 1.8}^{+ 1.7}$ km s $^{- 1} Mpc^{- 1}$ , describing deflector mass density pro…
