Measuring the Hubble constant with lens time delays in inhomogeneous universes


Abstract

With light curve measurements, their statistical analysis, time delays and lens models all improving so that people are talking about 1% accuracy in measuring the Hubble constant with gravitational lenses, I took the opportunity of the Jodrell Bank `Golden Lenses' workshop to point out that, at this level of accuracy, one must take the other cosmological parameters, especially the inhomogeneity parameter, into account.
