Description
Strong gravitational lenses with measured time delays between the multiple lensed images provide an effective way to measure the Hubble constant H0, a key cosmological parameter that sets the expansion rate of the Universe. Lensed quasars with exquisite observations have been used to measure H0, providing competitive results. Exciting discoveries of the first strongly lensed supernovae are starting to yield H0 measurements. In this presentation, I will provide an overview of recent H0 measurements from both lensed quasars and lensed supernovae. I will show the bright prospects of lensed transients as an independent and competitive cosmological probe.
