ABSTRACT: Strongly lensed supernovae are highly valuable cosmological probes, sensitive to both the Hubble constant and the distribution of dark matter. Measuring time delays in strong lensing systems allows for independent measurements of the Hubble constant, providing a mechanism to resolve the current Hubble tension. These time delays are also sensitive to the dark matter […]
