Fractional Action Cosmology: Some Dark Energy Models in Emergent, Logamediate and Intermediate Scenarios of the Universe
Fractional Action Cosmology Dark Energy Model Emergent Logamediate Intermediate Scenarios of the Universe
2011/8/2
Abstract: In the framework of Fractional Action Cosmology, we have reconstructed the scalar potentials and scalar fields, namely, quintessence, phantom, tachyon, k-essence, DBI-essence, Hessence, dila...
Statefinder Description in Generalized Holographic and Ricci Dark Energy Models
Statefinder Ricci Dark Energy Models
2011/9/7
We have considered the generalized holographic and generalized Ricci dark energy models for acceleration of the universe. If the universe filled with only GHDE/GRDE the corresponding decel-eration par...
Study of Thermodynamics in Generalized Holographic and Ricci Dark Energy Models
Thermodynamics Holographic and Ricci Dark Energy Models
2011/9/6
We have considered the flat FRW model of the universe which is filled with the combination of dark matter and dark energy. Here we have considered two types of dark energy models: (i)Generalized holog...
ISW-LSS cross-correlation in coupled Dark Energy models with massive neutrinos
cosmic microwave background cosmology: miscellaneous cosmology observations cosmology: theory cosmology: large-scale structure of universe
2010/11/9
We provide an exhaustive analysis of the Integrated Sach–Wolfe effect (ISW) in the context of coupled Dark Energy cosmologies where a component of massive neutrinos is also present. We focus on the ef...
Characters of current type Ia supernovae data based on evolving dark energy models
dark energy theory supernova type Ia - standard candles cosmological param-eters from CMBR
2010/11/11
We study characters of recent type Ia supernova (SNIa) data using evolving dark energy models with changing equation of state parameter w. We consider sudden-jump approximation of w for some chosen re...
Correspondence between entropy-corrected holographic and Gauss-Bonnet dark energy models
Correspondence between entropy-corrected holographic Gauss-Bonnet dark energy models
2010/12/20
In the present work we investigate the cosmological implications of the entropy-corrected
holographic dark energy (ECHDE) density in the Gauss-Bonnet framework. This is motivated
from the loop quant...
Interacting agegraphic dark energy models in phase space
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc) High Energy Physics - Phenomenology (hep-ph) High Energy Physics - Theory (hep-th)
2010/12/23
Agegraphic dark energy, has been recently proposed, based on the so-called Karolyhazy uncertainty relation, which arises from quantum mechanics together with general relativity. In the first part of t...
Attractors in Dark Energy Models with Born-Infeld Scalar Field
Dark Energy Models Born-Infeld Scalar Field
2010/10/15
We derive, in the large scale limit, analytical solutions for a dark energy model described by the Born-Infeld field plus a perfect fluid, both for homogeneous background and first order perturbations...
