Can late-time extensions solve the and tensions?
L Heisenberg, H Villarrubia-Rojo, J Zosso - Physical Review D, 2022 - APS
We analyze the properties that any late-time modification of the Λ CDM expansion history
must have in order to consistently solve both the H 0 and the σ 8 tensions. Taking a model …

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 …
