The Coincidence Problem and Interacting Holographic Dark Energy
Khamphee Karwan
We study the dynamical behaviour of the interacting holographic dark energy model whose interaction term is $Q=3H(\lam_dρ_d + \lam_cρ_c)$, where and are the energy dens…

A Model of Large Quintessence Isocurvature Fluctuations and Low CMB Quadrupole
Khamphee Karwan
Based on quintessence models with anticorrelation between the quintessence fluctuations and adiabatic perturbations in the other matter components, we show that if the quintessence…

Observational constraints on the dark energy density evolution
Michael Doran, Khamphee Karwan, Christof Wetterich
We constrain the evolution of the dark energy density from Cosmic Microwave Background, Large Scale Structure and Supernovae Ia measurements. While Supernovae Ia are most sensitive…
