The contribution from small scales on two-point shear analysis: comparison between power spectrum and correlation function
João Ferri, Elisa G. M. Ferreira, Ryo Terasawa
A known problem in cosmic shear two-point statistics is the apparent inconsistency between analyses performed in harmonic space (power spectrum) and real space (angular correlation…

First measurement of the Hubble constant from gravitational wave-galaxy cross-correlations
Isabela Santiago de Matos, Charles Dalang, Tessa Baker +4
We measure for the first time the Hubble constant () from the cross-correlation of galaxies and gravitational waves (GW), by applying the method. This m…

A robust cosmic standard ruler from the cross-correlations of galaxies and dark sirens
João Ferri, Ian L. Tashiro, L. Raul Abramo +3
Observations of gravitational waves (GWs) from dark sirens allow us to infer their locations and distances. Galaxies, on the other hand, have precise angular positions but no direc…
