How does the cosmic large-scale structure bias the Hubble diagram?
Pierre Fleury, Chris Clarkson, Roy Maartens
The Hubble diagram is one of the cornerstones of observational cosmology. It is usually analysed assuming that, on average, the underlying relation between magnitude and redshift m…
Cosmic backreaction and Gauss's law
Pierre Fleury
Cosmic backreaction refers to the general question of whether a homogeneous and isotropic cosmological model is able to predict the correct expansion dynamics of our inhomogeneous…
On the time delay between ultra-relativistic particles
Pierre Fleury
The time delay between the receptions of ultra-relativistic particles emitted simultaneously is a useful observable for both fundamental physics and cosmology. The expression of th…
Geodesic-light-cone coordinates and the Bianchi I spacetime
Pierre Fleury, Fabien Nugier, Giuseppe Fanizza
The geodesic-light-cone (GLC) coordinates are a useful tool to analyse light propagation and observations in cosmological models. In this article, we propose a detailed, pedagogica…
