Constraining power of cosmological observables: blind redshift spots and optimal ranges

L. Kazantzidis, L. Perivolaropoulos, F. Skara

A cosmological observable measured in a range of redshifts can be used as a probe of a set of cosmological parameters. Given the cosmological observable and the cosmological parame…

Consistency of Modified Gravity with a decreasing $G_{eff} (z)$ in a $Λ$ CDM background

Radouane Gannouji, Lavrentios Kazantzidis, Leandros Perivolaropoulos +1

Recent analyses \cite{Nesseris:2017vor,Kazantzidis:2018rnb} have indicated that an effective Newton's constant $G_{eff} (z)$ decreasing with redshift may relieve the observed te…

Evolution of the $f σ_{8}$ tension with the Planck15/ $Λ$ CDM determination and implications for modified gravity theories

Lavrentios Kazantzidis, Leandros Perivolaropoulos

We construct an updated extended compilation of distinct (but possibly correlated) $f σ_{8} (z)$ Redshift Space Distortion (RSD) data published between 2006 and 2018. It consists of 63…
