Description

Abstract: Gravitational-wave (GW) cosmology has recently been established as a new observationally-driven research field, and is expected to expand rapidly in the future thanks to the increasing number of ever more accurate GW observations. In this talk I will review the current status of GW cosmological results obtained with the LIGO and Virgo interferometers, and will survey the results expected with future detectors. I will first introduce the most common methodologies employed to extract cosmological information from GW data, including new tests of LCDM which cannot be performed with more common electromagnetic observations. I will then show how these methods are employed to produce cosmological constraints with current GW data collected by LIGO and Virgo, and how they will usher an era of precise GW cosmology with next generation detectors, such as the Einstein Telescope on the Earth and LISA in space.
