TDCOSMO. I. An exploration of systematic uncertainties in the inference of $H_0$ from time-delay cosmography

M. Millon, A. Galan, F. Courbin +22

Time-delay cosmography of lensed quasars has achieved 2.4% precision on the measurement of the Hubble constant, $H_0$. As part of an ongoing effort to uncover and control systemati…
