BETOCS using the 157 gold SNe Ia Data : Hubble is not humble

R. Colistete, R. Giostri

The type Ia supernovae observational data is one of the most important in observational cosmology nowadays. Here we present the first public version of BETOCS (BayEsian Tools for O…

Bayesian Analysis of the (Generalized) Chaplygin Gas and Cosmological Constant Models using the 157 gold SNe Ia Data

R. Colistete, J. C. Fabris

The generalized Chaplygin gas model (GCGM) contains 5 free parameters, here, they are constrained through the type Ia supernovae data, i.e., the ``gold sample'' of 157 supernovae d…

Bayesian Statistics and Parameter Constraints on the Generalized Chaplygin Gas Model using SNe Ia Data

R. Colistete, J. C. Fabris, S. V. B. Goncalves

The type Ia supernovae (SNe Ia) observational data are used to estimate the parameters of a cosmological model with cold dark matter and the generalized Chaplygin gas model (GCGM).…

Bayesian Analysis of the Chaplygin Gas and Cosmological Constant Models using the SNe Ia Data

R. Colistete, J. C. Fabris, S. V. B. Gonçalves +1

The type Ia supernovae observational data are used to estimate the parameters of a cosmological model with cold dark matter and the Chaplygin gas. The Chaplygin gas model depends e…

Dark energy, dark matter and the Chaplygin gas

R. Colistete, J. C. Fabris, S. V. B. Goncalves +1

The possibility that the dark energy may be described by the Chaplygin gas is discussed. Some observational constraints are established. These observational constraints indicate th…

Constraints on Non-Singular Cosmological Models with Quadratic Lagrangians

R. Colistete

We consider the generalized set of theories of gravitation whose Lagrangians contain the term : . Inserting the RW metric with an imposed non-singula…
