Not all those missing are lost: leveraging galaxy clustering in incomplete catalogs to unleash dark sirens cosmology
Riccardo Barbieri, Marios Kalomenopoulos, Matteo Tagliazucchi +2
Gravitational waves offer a unique opportunity to solve the Hubble tension. In order to do so, we have to extract as much information as possible from cross correlating gravitation…

Enhancing dark siren cosmology via Gaussian process reconstruction of incomplete galaxy catalogs
Matteo Tagliazucchi, Jonathan Gair, Riccardo Barbieri +1
We present a novel framework for improving dark siren cosmology by applying a Gaussian process (GP) to the line-of-sight (LOS) reconstruction of incomplete galaxy catalogs. In the…

Clustering effects on the Dark Siren determination of : A simulation study
Marios Kalomenopoulos, Riccardo Barbieri, Sadegh Khochfar +2
Gravitational waves (GWs) offer an alternative way to measure the Hubble parameter. The optimal technique, the ``bright siren'' approach, requires the identification of an electrom…
