Interaction in the dark sector: a Bayesian analysis with latest observations
T. Ferreira, C. Pigozzo, S. Carneiro +1
By combining cosmological probes at low, intermediate and high redshifts, we investigate the observational viability of a class of models with interaction in the dark sector. We pe…
Screening mechanisms in hybrid metric-Palatini gravity
Marcelo Vargas dos Santos, Jailson S. Alcaniz, David F. Mota +1
We investigate the efficiency of screening mechanisms in the hybrid metric-Palatini gravity. The value of the field is computed around spherical bodies embedded in a background of…
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…
Isotropy of low redshift type Ia Supernovae: A Bayesian analysis
U. Andrade, C. A. P. Bengaly, J. S. Alcaniz +1
The standard cosmology strongly relies upon the Cosmological Principle, which consists on the hypotheses of large scale isotropy and homogeneity of the Universe. Testing these assu…
Observations of the first electromagnetic counterpart to a gravitational wave source by the TOROS collaboration
M. C. Díaz, L. M. Macri, D. Garcia Lambas +52
We present the results of prompt optical follow-up of the electromagnetic counterpart of the gravitational-wave event GW170817 by the Transient Optical Robotic Observatory of the S…
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…
