The and tensions and the scale invariant spectrum
Micol Benetti, Leila L. Graef, Jailson S. Alcaniz
In a previous communication we showed that a joint analysis of Cosmic Microwave Background (CMB) data and the current measurement of the local expansion rate favours a model with a…
Constraining the Break of Spatial Diffeomorphism Invariance with Planck Data
L. L. Graef, M. Benetti, J. S. Alcaniz
The current most accepted paradigm for the early universe cosmology, the inflationary scenario, shows a good agreement with the recent Cosmic Microwave Background (CMB) and polariz…
Do joint CMB and HST data support a scale invariant spectrum?
Micol Benetti, Leila L. Graef, Jailson S. Alcaniz
We combine current measurements of the local expansion rate, , and Big Bang Nucleosynthesis (BBN) estimates of helium abundance with the latest cosmic microwave background (CM…
Dynamics of Cosmological Perturbations and Reheating in the Anamorphic Universe
L. L. Graef, W. S. Hipolito-Ricaldi, Elisa G. M. Ferreira +1
We discuss scalar-tensor realizations of the Anamorphic cosmological scenario recently proposed by Ijjas and Steinhardt. Through an analysis of the dynamics of cosmological perturb…
