Age constraints on the Agegraphic Dark Energy Model
Yi Zhang, Hui Li, Xing Wu +2
We investigate the age constraint on the agegraphic dark energy model by using two old galaxies (LBDS 53W091 and LBDS 53W069) and the old high redshift quasar APM 08279+5255. We fi…
Cosmological Constraints on New Agegraphic Dark Energy
Hao Wei, Rong-Gen Cai
In this work, we consider the cosmological constraints on the new agegraphic dark energy (NADE) proposed in arXiv:0708.0884, by using the observational data of type Ia supernovae (…
A New Model of Agegraphic Dark Energy
Hao Wei, Rong-Gen Cai
In this note, we propose a new model of agegraphic dark energy based on the Károlyházy relation, where the time scale is chosen to be the conformal time of the Friedmann-Robert…
Statefinder Diagnostic and w-w' Analysis for the Agegraphic Dark Energy Models without and with Interaction
Hao Wei, Rong-Gen Cai
A new dark energy model, named as ``agegraphic dark energy'', has been proposed by one of us (R. G. Cai) in arXiv:0707.4049, based on the Károlyházy uncertainty relation, which ari…
Interacting Agegraphic Dark Energy
Hao Wei, Rong-Gen Cai
A new dark energy model, named "agegraphic dark energy", has been proposed recently, based on the so-called Károlyházy uncertainty relation, which arises from quantum mechanics tog…
Age Problem in the Holographic Dark Energy Model
Hao Wei, Shuang Nan Zhang
In this note, we test the original holographic dark energy model with some old high redshift objects. The main idea is very simple: the universe cannot be younger than its constitu…
Dynamics of Quintom and Hessence Energies in Loop Quantum Cosmology
Hao Wei, Shuang Nan Zhang
In the present work, we investigate the universe dominated by quintom or hessence energies in Loop Quantum Cosmology (LQC). Interestingly enough, we find that there are some stable…
Interacting Energy Components and Observational Data
Hao Wei, Shuang Nan Zhang
In this note, we extend our previous work [Phys. Lett. B 644, 7 (2007), astro-ph/0609597], and compare eleven interacting dark energy models with different couplings to the observa…
