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${}^{-1}{\mathrm{Mpc}}^{-1}$, describing deflector mass density pro…
