Backreaction and the Role of Spatial Curvature in the Cosmic Neighborhood
Marco Galoppo, Thomas Buchert, Pierre Mourier
We present the first direct computation of spatially averaged dynamical quantities in the local Universe, employing the Cosmicflows-4++ reconstruction and a covariant scalar averag…
An effective -Szekeres modelling of the local Universe with Cosmicflows-4
Marco Galoppo, Leonardo Giani, Morag Hills +1
We develop an effective description of the local cosmic environment, namely, for redshift , to quantify the bias induced by local structure on cosmological observab…
Supernovae evidence for foundational change to cosmological models
Antonia Seifert, Zachary G. Lane, Marco Galoppo +2
We present a new, cosmologically model-independent, statistical analysis of the Pantheon+ type Ia supernovae spectroscopic dataset, improving a standard methodology adopted by Lane…
