Timing the cosmic expansion with gravitational-waves dark sirens: from compact binaries to large scale structures

For 20 years, measurements of the Universe expansion rate from close-by and far sources are in tension hinting at the presence of new physics. Our struggle to study the Universe's expansion is due to the difficulty of observing cosmological sources for which the distance is known. Gravitational Waves (GWs) from compact binary coalescences (CBCs) are emergent cosmological probes that provide directly the distance of the source thus taking the name of Standard Sirens. Unfortunately, they do not provide the other ingredient to measure the Universe expansion: the redshift. GravitySirens is an ambitious project aiming to measure the cosmic expansion with CBCs and exploit their link with the…
