Measuring the Hubble Constant Near and Far in the Era of ELT's
Abstract
Despite great progress, controversy remains regarding H0. New techniques for measuring H0 have come-of-age in this decade. In the next decade, the combination of ELTs and other ground-based facilities using these techniques will transform measurement of H0. The techniques are described, with a focus on how to realize a 1% measure of H0 with each.
