Measuring the Hubble Constant with Gravitational Waves

The first detection of binary neutron star merger by Advanced LIGO-Virgo and the discovery of the optical counterpart allowed for the first independent measurement of Hubble constant with gravitational waves. In this talk, I will summarize latest cosmological measurements with gravitational waves, and discuss the future aspects of them. I will then talk about the potential challenges and how we improve the measurements.
