Description
This lecture explores the use of strongly-lensed quasars to measure the Hubble constant and time-delay distances, providing insights into the expansion history of the universe and the nature of dark energy. By combining time delay distances from multiple lenses, a cosmological probe is created to constrain the model's parameters, showcasing the tension between different measurement techniques and the potential implications for our understanding of the universe.
