The second-order luminosity-redshift relation in a generic inhomogeneous cosmology
Ido Ben-Dayan, Giovanni Marozzi, Fabien Nugier +1
After recalling a general non-perturbative expression for the luminosity-redshift relation holding in a recently proposed "geodesic light-cone" gauge, we show how it can be transfo…
Do stochastic inhomogeneities affect dark-energy precision measurements?
Ido Ben-Dayan, Maurizio Gasperini, Giovanni Marozzi +2
The effect of a stochastic background of cosmological perturbations on the luminosity-redshift relation is computed to second order through a recently proposed covariant and gauge-…
Backreaction on the luminosity-redshift relation from gauge invariant light-cone averaging
Ido Ben-Dayan, Maurizio Gasperini, Giovanni Marozzi +2
Using a recently proposed gauge invariant formulation of light-cone averaging, together with adapted "geodesic light-cone" coordinates, we show how an "induced backreaction" effect…
