Nonlinear Relativistic Effects on Cosmological Redshift Drift
Pierre Béchaz, Giuseppe Fanizza, Giovanni Marozzi +1
Using a fully gauge-invariant approach, we compute for the first time in the literature relativistic effects on the redshift drift up to second order in cosmological perturbation t…

A Light-Cone Approach to Higher-Order Cosmological Observables
Pierre Béchaz, Giuseppe Fanizza, Giovanni Marozzi +1
We develop a second-order cosmological perturbation theory on a background geometry expressed in terms of light-cone coordinates, extending the first-order analyses available in th…
