Description

The Hubble constant (H0) is a key parameter in cosmology that sets the expansion rate and the age of the Universe. Independent determinations of H0 are important to ascertain the possible need of new physics beyond the standard cosmological model, given the tension in current H0 measurements from the cosmic microwave background observations of Planck and the local distance ladder from the SH0ES program. I will give an overview of recent H0 measurements from different methods, with a focus on strong gravitational lensing as a competitive cosmological probe.
