# Summary of cosmology with gravitational waves from compact binary coalescences

## TL;DR

This paper reviews how gravitational waves from compact binary coalescences are used to measure the universe's expansion rate, highlighting recent results and future prospects with advanced detectors.

## Contribution

It summarizes recent gravitational-wave measurements of the Hubble constant and discusses future observational prospects with the LIGO-Virgo network.

## Key findings

- GW170817 provided a standard siren measurement of Hubble constant
- Statistical methods are beginning to yield independent estimates
- Upcoming detector runs will improve measurement precision

## Abstract

GW170817 with its coincident optical counterpart has led to a first "standard siren" measurement of the Hubble constant independent of the cosmological distance ladder. The Schutz "statistical" method, which is expected to work in the absence of uniquely identified hosts, has also started bringing in its first estimates. In this work we report the current results of the gravitational-wave measurement of the Hubble constant and discuss the prospects with observations during the upcoming runs of the Advanced LIGO-Virgo detector network.
