A Systematic Literature Review of Machine Learning Techniques for Observational Constraints in Cosmology
Luis Rojas, Sebastián Espinoza, Esteban González +2
This paper presents a systematic literature review focusing on the application of machine learning techniques for deriving observational constraints in cosmology. The goal is to ev…
Dynamics and statefinder analysis of a class of sign-changeable interacting dark energy scenarios
Fabiola Arevalo, Antonella Cid
We revise the dynamical properties of a class of cosmological models where the dark sector interacts through an interacting term that changes sign during evolution. In particular,…
Bayesian Comparison of Interacting Modified Holographic Ricci Dark Energy Scenarios
Antonella Cid, Carlos Rodriguez-Benites, Mauricio Cataldo +1
We perform a Bayesian model selection analysis for interacting scenarios of dark matter and modified holographic Ricci dark energy (MHRDE) with linear interacting terms. We use a c…
Bayesian Comparison of Interacting Scenarios
Antonella Cid, Beethoven Santos, Cassio Pigozzo +2
We perform a Bayesian model selection analysis for different classes of phenomenological coupled scenarios of dark matter and dark energy with linear and non-linear interacting ter…
AIC and BIC for cosmological interacting scenarios
Fabiola Arevalo, Antonella Cid, Jorge Moya
In this work we study linear and non-linear cosmological interactions, which depend on dark matter and dark energy densities in the framework of General Relativity. By using the Ak…
The Emergent Universe scheme and Tunneling
Pedro Labrana
We present an alternative scheme for an Emergent Universe scenario, developed previously in , where the universe is initially in a static st…
Emergent universe scenario and the low CMB multipoles
Pedro Labrana
In this work we study superinflation in the context of the emergent universe (EU) scenario. The existence of a superinflating phase before the onset of slow-roll inflation arises i…
Connecting The Non-Singular Origin of the Universe, The Vacuum Structure and The Cosmological Constant Problem
Eduardo Guendelman, Pedro Labrana
We consider a non-singular origin for the Universe starting from an Einstein static Universe, the so called "emergent universe" scenario, in the framework of a theory which uses tw…
Intermediate Inflation in the Jordan-Brans-Dicke Theory
Antonella Cid, Sergio del Campo
We present an intermediate inflationary stage in a Jordan-Brans-Dicke theory. In this scenario we analyze the quantum fluctuations corresponding to adiabatic and isocurvature modes…
Observational constraints on a cosmological model with Lagrange multipliers
Antonella Cid, Pedro Labrana
Cosmological models with Lagrange multipliers are appealing because they could explain the behaviour of the dark sector in a unified way. In this work we analyse extensions to the…
Emergent Universe from Scale Invariant Two Measures Theory
Sergio del Campo, Eduardo I. Guendelman, Alexander B. Kaganovich +2
The dilaton-gravity sector of a linear in the scalar curvature, scale invariant Two Measures Field Theory (TMT), is explored in detail in the context of closed FRW cosmology and sh…
Constraints from CMB in the intermediate Brans-Dicke inflation
Antonella Cid, Sergio del Campo
We study an intermediate inflationary stage in a Jordan-Brans-Dicke theory. In this scenario we analyze the quantum fluctuations corresponding to adiabatic and isocurvature modes.…
Crossing the phantom divide with a classical Dirac field
Mauricio Cataldo, Luis Chimento
In this paper we consider a spatially flat Friedmann-Robertson-Walker (FRW) cosmological model with cosmological constant, containing a stiff fluid and a classical Dirac field. The…
Emerging Universe from Scale Invariance
Sergio del Campo, Eduardo Guendelman, Ramon Herrera +1
We consider a scale invariant model which includes a term in action and show that a stable "emerging universe" scenario is possible. The model belongs to the general class…
On a class of scaling FRW cosmological models
Mauricio Cataldo, Fabiola Arevalo, Paul Minning
We study Friedmann-Robertson-Walker cosmological models with matter content composed of two perfect fluids and , with barotropic pressure densities …
