Late-time and Big Bang nucleosynthesis constraints for generic modify gravity surveys
N. M. Jiménez Cruz, Celia Escamilla-Rivera
In this work, a new generic parameterisation for theories is presented. Our proposal for a new equation of state can reproduce an -like evolution that describes late a…
Precision Cosmology in Modified and Extended Theories of Gravity: an insightful test
Celia Escamilla-Rivera
In this work we present a brief discussion about modified and extended cosmological models using current observational tests. We show that according to these astrophysical samples…
Cosmology Intertwined II: The Hubble Constant Tension
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +90
The current cosmological probes have provided a fantastic confirmation of the standard Cold Dark Matter cosmological model, that has been constrained with unprecedented accurac…
Observational constraints on complex quintessence with attractive self-interaction
Belen Carvente, Víctor Jaramillo, Celia Escamilla-Rivera +1
In this paper we consider that dark energy could be described solely by a complex scalar field with a Bose-Einstein condensate-like potential (denoted as CSFDE), that is, with a se…
Dark energy as generalised superfluid excitations
Elías Castellanos, Celia Escamilla-Rivera
In this paper we present a generic form of the cosmological Equation of State derived from the formalism of Statistical Mechanics, assuming that a cosmic acceleration scenario can…
Bayesian deep learning for dark energy
Celia Escamilla-Rivera
In this work we discuss basic ideas on how to structure and study the Bayesian methods for standard models of dark energy and how to implement them in the architecture of deep lear…
Stability analysis for cosmological models in gravity
Geovanny A. Rave Franco, Celia Escamilla-Rivera, Jackson Levi Said
In this paper we study cosmological solutions of the gravity using dynamical system analyses. For this purpose we consider cosmological viable functions of that a…
Linear perturbations spectra for dynamical dark energy inspired by modified gravity
Celia Escamilla-Rivera, A. Hernández-Almada, Miguel A. García-Aspeitia +1
In this paper, we study a particular modified gravity Equation of State, the so-called Jaime-Jaber-Escamilla, that emerges from the first gravity modified action principle and can…
The Possibility of a Non-Lagrangian Theory of Gravity
Celia Escamilla-Rivera, Júlio C. Fabris
General Relativity resembles a very elegant crystal glass: If we touch its principles, that is, its Lagrangian, there is a risk of breaking everything. Or, if we will, it is like a…
Quantum signatures from Horava-Lifshitz cosmography
Celia Escamilla-Rivera, Hernando Quevedo
In this paper we propose an alternative cosmography by considering Horava-Lifshitz gravity as a model of quantum gravity to search for quantum effects at the cosmological level. Fo…
Inverse Cosmography: testing the effectiveness of cosmographic polynomials using machine learning
Cristian Zamora Munõz, Celia Escamilla-Rivera
Cosmography has been referred to as a solution to the inverse scattering problem, which is reasonable since it allows us to calculate cosmological bounds from data samplers by perf…
Constraining extra dimensions on cosmological scales with LISA future gravitational wave siren data
Maxence Corman, Celia Escamilla-Rivera, M. A. Hendry
We investigate the idea that current cosmic acceleration could be the consequence of gravitational leakage into extra dimensions on cosmological scales rather than the result of a…
Gravitational waves in braneworlds after multi-messenger events
Miguel A. García-Aspeitia, Celia Escamilla-Rivera
The GW170817 event opened a new window to test modifications to General Relativity with the aim of discard or impose strong constraints in extra dimension theories of gravity. Conc…
