Cosmological constraints on -corrected Appleby-Battye model
Bruno Ribeiro, Armando Bernui, Marcela Campista
Nowadays, efforts are being devoted to the study of alternative cosmological scenarios in which modifications of General Relativity have been proposed to explain the late cosmic ac…
Observational constraints on Starobinsky cosmology from cosmic expansion and structure growth data
Pedro Bessa, Marcela Campista, Armando Bernui
The unknown physical nature of the Dark Energy motivates in cosmology the study of modifications of the gravity theory at large distances. One of these types of modifications is to…
Probing the Seesaw Mechanism with Cosmological Data
J. G. Rodrigues, Micol Benetti, Marcela Campista +1
We investigate cosmological consequences of an inflationary model which incorporates a generic seesaw extension (types I and II) of the Standard Model of Particle Physics. A non-mi…
Vacuum solutions in the Einstein-Aether Theory
M. Campista, R. Chan, M. F. A. da Silva +3
The Einstein-Aether (EA) theory belongs to a class of modified gravity theories characterized by the introduction of a time-like unit vector field, called aether. In this scenario,…
Testing non-minimally coupled inflation with CMB data: a Bayesian analysis
Marcela Campista, Micol Benetti, Jailson Alcaniz
We use the most recent cosmic microwave background (CMB) data to perform a Bayesian statistical analysis and discuss the observational viability of inflationary models with a non-m…
J-PAS: The Javalambre-Physics of the Accelerated Universe Astrophysical Survey
N. Benitez, R. Dupke, M. Moles +149
The Javalambre-Physics of the Accelerated Universe Astrophysical Survey (J-PAS) is a narrow band, very wide field Cosmological Survey to be carried out from the Javalambre Observat…
Cosmology with Hu-Sawicki gravity in Palatini Formalism
B. Santos, M. Campista, J. Santos +1
Cosmological models based on f(R)-gravity may exhibit a natural acceleration mechanism without introducing a dark energy component. In this paper, we investigate cosmological conse…
Cosmological Consequences of Exponential Gravity in Palatini Formalism
M. Campista, B. Santos, J. Santos +1
We investigate cosmological consequences of a class of exponential gravity in the Palatini formalism. By using the current largest type Ia Supernova sample along with determ…
