Holography and matter creation revisited
V. H. Cárdenas, Miguel Cruz, Samuel Lepe
The consideration of the holographic dark energy approach and matter creation effects in a single cosmological model is carried out in this work accordingly, we discuss some cases…
Parametric and nonparametric methods hint dark energy evolution
Reginald Christian Bernardo, Daniela Grandón, Jackson Levi Said +1
We study dark energy through the viewpoints of parametric and nonparametric analyses of late-time cosmological data. We consider four Hubble parameter priors reflecting the Hubble…
Matter production effects and interacting scenario within a reconstructed mimetic cosmology for late times
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe
In this work we explore two possible scenarios that can be considered to extend a recent proposed model by the authors known as reconstructed mimetic cosmology. This study is compl…
Reconstructing Mimetic Cosmology
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe +1
We explore the mimetic gravity formulation with the inclusion of a scalar field potential namely, . However, we are not considering any {\it a priori} specific form this term…
Cosmic expansion with matter creation and bulk viscosity
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe
We explore the cosmological implications at effective level of matter creation effects in a dissipative fluid for a FLRW geometry; we also perform a statistical analysis for this k…
Challenging matter creation models in the phantom divide
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe +2
We perform a study both statistical and theoretical for cosmological models of matter creation and their ability to describe effective phantom models of dark energy. Such models ar…
Stealth's cosmologies
Abigail Alvarez, Cuauhtemoc Campuzano, Víctor Cárdenas +1
We present a novel approach to construct cosmological models endowed with a particular scalar field, the stealth. The model is constructed by studying a scalar field no-minimally c…
Cherenkov Telescope Array Contributions to the 35th International Cosmic Ray Conference (ICRC2017)
F. Acero, B. S. Acharya, V. Acín Portella +1137
List of contributions from the Cherenkov Telescope Array Consortium presented at the 35th International Cosmic Ray Conference, July 12-20 2017, Busan, Korea.
Science with the Cherenkov Telescope Array
The Cherenkov Telescope Array Consortium, :, B. S. Acharya +580
The Cherenkov Telescope Array, CTA, will be the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond. The scientific potential of CTA i…
Semi-holographic model including the radiation component
Sergio del Campo, Víctor Cárdenas, Juan Magaña +1
In this letter we study the semi holographic model which corresponds to the radiative version of the model proposed by Zhang et al. (Phys. Lett. B 694 (2010), 177) and revisited by…
Cosmic slowing down of acceleration for several dark energy parametrizations
Juan Magaña, Víctor H. Cárdenas, V. Motta
We further investigate slowing down of acceleration of the universe scenario for five parametrizations of the equation of state of dark energy using four sets of supernovae data. I…
Semi-holographic model revisited
Víctor H. Cárdenas, J. R. Villanueva, Juan Magaña
In a recent work Zhang, Li and Noh [Phys. Lett. B {\bf 694}, 177 (2010)]proposed a model for dark energy assuming this component strictly obeys the holographic principle. They perf…
Chaos and Preheating
Sergio E. Jorás, Victor H. Cárdenas
We show evidence for a relationship between chaos and parametric resonance both in a classical system and in the semiclassical process of particle creation. We apply our considerat…
