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…
Fisher matrix for the angular power spectrum of multi-tracer galaxy surveys
L. Raul Abramo, João Ferri, Ian Tashiro +1
Redshift evolution and peculiar velocities break the isotropy of cosmological surveys with respect to the directions parallel and transverse to the line of sight, limiting the accu…
Fisher matrix for multiple tracers: the information in the cross-spectra
L. Raul Abramo, Ian L. Tashiro, João V. D. Ferri
We derive general expressions for the multi-tracer Fisher matrix, both assuming that the cross-spectra are constrained by the auto-spectra, and also allowing for independent degree…
