LensWatch :

The LensWatch collaboration is an international group of astronomers searching for lensed SNe with targeted surveys of known strong-lensing systems (galaxies and clusters). We have been awarded a 3-year HST Target of Opportunity program, beginning in Cycle 28, for follow-up of any lensed SN candidate. The primary science goal is to classify the lensed SN and measure the gravitational lensing time delay to measure the Hubble-LeMaître constant, H0.

Collaboration: who we are
