Title |
The geodesic light-cone coordinates, an adapted system for light-signal-based cosmology | |||||
Coauthors | ||||||||
Abstract |
Most of cosmological observables are light-propagated. I will present coordinates adapted to the propagation of null-like signals as observed by a geodesic observer. These ``geodesic light-cone (GLC) coordinates'' are general, adapted to calculations in inhomogeneous geometries, and their properties make them useful for a large spectrum of applications, from the average on our past light cone, the estimation of the distance-redshift relation, the effect of the large-scale structure on the Hubble diagram, to weak lensing calculations. |
