Time-delay cosmography for measuring the Hubble constant

COSMICLENS is an extension of the COSMOGRAIL program to measure H0 with time delays in gravitationally lensed quasars. Funded with an ERC Advanced grant in 2018, it proposes to implement lens monitoring at high temporal cadence with a 2m-class telescope and to measure time delays with unprecedented precision and accuracy. The project also focuses on new modelling techniques, source reconstruction techniques and of course on finding new lensed systems suitable for such studies.
