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…
A Bayesian analysis of inflationary primordial spectrum models using Planck data
Simony Santos da Costa, Micol Benetti, Jailson Alcaniz
The current available CMB data show an anomalously low value of the CMB temperature fluctuations at large angular scales (l < 40). This lack of power is not explained by the minima…
CMB constraints on -exponential inflationary models
M. A. Santos, M. Benetti, J. S. Alcaniz +2
We analyze a class of generalized inflationary models proposed in Ref. [1], known as -exponential inflation. We show that this kind of potential can arise in the context of bran…
Constraining quantum collapse inflationary models with current data: The semiclassical approach
María Pía Piccirilli, Gabriel León, Susana J. Landau +2
The hypothesis of the self-induced collapse of the inflaton wave function was introduced as a candidate for the physical process responsible for the emergence of inhomogeneity and…
Measuring the transverse baryonic acoustic scale from the SDSS DR11 galaxies
G. C. Carvalho, A. Bernui, M. Benetti +3
We report five measurements of the transverse baryonic acoustic scale, , obtained from the angular two-point correlation function calculation for Luminous Red Galaxies of…
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…
