Implications for cosmology following recent gravitational wave observations
Résumé
Standard sirens are a central paradigm in gravitational-wave (GW) cosmology.From the GW signature detected from compact binary mergers, it is possible todirectly measure the luminosity distance of the source, and if additionalinformation on the source redshift is provided, a measurement of thecosmological expansion can be performed. In this article, I will provide anintuitive introduction to current analysis methods for GW standard sirencosmology. I will also present the most recent results on cosmology using thelatest LIGO-Virgo-KAGRA GW events.
