High-Redshift Cosmography
Vincenzo Vitagliano, Jun-Qing Xia, Stefano Liberati +1
We constrain the parameters describing the kinematical state of the universe using a cosmographic approach, which is fundamental in that it requires a very minimal set of assumptio…

Averaging inhomogeneities in scalar-tensor cosmology
Vincenzo Vitagliano, Stefano Liberati, Valerio Faraoni
The backreaction of inhomogeneities on the cosmic dynamics is studied in the context of scalar-tensor gravity. Due to terms of indefinite sign in the non-canonical effective energy…
