Evidence for suppression of structure growth in the concordance cosmological model
We present evidence for a suppressed growth rate of large-scale structure during the dark-
energy-dominated era. Modeling the growth rate of perturbations with the “growth index” γ …

tension, phantom dark energy, and cosmological parameter degeneracies
G Alestas, L Kazantzidis, L Perivolaropoulos - Physical Review D, 2020 - APS
Phantom dark energy (w<-1) can produce amplified cosmic acceleration at late times, thus
increasing the value of H 0 favored by CMB data and releasing the tension with local …

Rapid transition of at as a possible solution of the Hubble and growth tensions
V Marra, L Perivolaropoulos - Physical Review D, 2021 - APS
The mismatch in the value of the Hubble constant from low-and high-redshift observations
may be recast as a discrepancy between the low-and high-redshift determinations of the …
